Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Cara Menghitung Volume Kubus Dan Limas

Untuk konsep dasar cara menghitung volume kubus dan limas sanggup dibaca pada postingan cecunguk online yang berjudul “Cara Menghitung Volume Kubus” dan “Cara Menghitung Volume Limas”. Pada postingan kali ini, Mafia Online kembali akan mengulas wacana volume kubus dan limas, tetapi ada perhiasan teladan soal kombinasi antara kubus dan limas yang lebih menantang.

Menghitung Volume Kubus

Kubus merupakan bidang enam beraturan yang mempunyai panjang rusuk yang sama di mana tiap bidangnya berbentuk persegi. Untuk menghitung volume kubus sanggup dipakai persamaan pada umumnya:

V = luas bantalan x tinggi

karena luas bantalan berbentuk persegi dengan panjang sisi (s) dan mempunyai tinggi yang sama dengan panjang sisinya maka volume kubus sanggup ditulis dengan persamaan:
V = s2 × s
V = s3

Untuk memantapkan pemahaman Anda wacana cara menghitung volume kubus, silahkan simak teladan soal di bawah ini.

Contoh Soal 1
Sebuah kubus mempunyai panjang diagonal ruang 12 cm. Tentukan volume kubus tersebut.

Penyelesaian:
Untuk menghitung volume kubus kita harus cari panjang sisi kubus terlebih dahulu dengan memakai rumus panjang diagonal ruang kubus yakni:
d = s√3
s = d/√3
s = 12/√3
s = 4√3 cm

Volume kubus sanggup dihitung dengan rumus:
V = s3
V = (4√3 cm)3
V = 192√3 cm3
Jadi, volume kubus tersebut ialah 192√3 cm3

Menghitung Volume Limas

Limas merupakan berdiri ruang yang alasnya berbentuk segi banyak (segitiga, segi empat, segi lima, dan seterusnya) dan bidang sisi tegaknya berbentuk segitiga yang berpotongan pada satu titik. Titik potong dari sisi-sisi tegak limas disebut klimaks limas. Untuk menghitung volume limas sanggup memakai rumus:
V = 1/3 × luas bantalan × tinggi

Untuk memantapkan pemahaman Anda wacana cara menghitung volume limas silahkan simak teladan soal di bawah ini.

Contoh Soal 2
Sebuah limas segiempat beraturan mempunyai rusuk 12 cm, tentukan volume limas tersebut.

Penyelesaian:
Perhatikan gambar di bawah ini.

Cara I (cara manual):
KM2 = KL2 + LM2
KM2 = 122 + 122
KM = 12√2 cm
dan
OM = ½ KM = 6√2 cm

Sekarang cari tinggi limas (OT) yakni:
OT2 = MT2 – OM2
OT2 = 122 – (6√2)2
OT2 = 72
OT = 6√2

Volume limas sanggup dihitung dengan rumus:
V = (1/3)×KL×LM×OT
V = (1/3)×12×12×6√2
V = 288√2 cm3

Cara I (cara cepat):
V = (1/6)s3√2
V = (1/6)(12 cm)3√2
V = 288√2 cm3
Jadi, volume limas tersebut ialah 288√2 cm3

Selain ibarat teladan soal di atas, kita juga sering diagadapkan dengan soal yang merupakan kombinasi antara kubus dan limas, ibarat teladan soal di bawah ini.

Contoh Soal 3
Sebuah kotak berbentuk kubus dengan panjang rusuk 12 cm diisi air sampai penuh. Kemudian dimasukan sebuah berdiri limas padat yang luas alasnya sama dengan luas bantalan kubus, sedangkan tinggi limas sama dengan setengah tinggi kubus. Akibatnya air yang ada di dalam kubus sebagian tumpah. Tentukan volume air yang masih di dalam gelas.

Penyelesaian:
Volume air yang ada di dalam kubus sama dengan volume kubus yakni:
V kubus = s2
V kubus = (12 cm)3
V kubus = 1728 cm3
Volume air yang tumpah sama dengan volume limas. Terlebih dahulu kita harus cari luas bantalan dan tinggi limas. Untuk mencari luas bantalan limas sanggup memakai rumus luas persegi yakni:
L = s2
L = (12 cm)2
L = 144 cm2
Sedangkan tinggi limas:
t = ½ × tinggi kubus
t = ½ × 12 cm
t = 6 cm
maka:
Volume limas sanggup dicari dengan rumus:
V limas = 1/3 × luas bantalan × tinggi
V limas = 1/3 × 144 cm2 × 6 cm
V limas = 288 cm3

Volume air yang masih tersisa di dalam kubus sanggup dicari dengan cara mengurangkan volume kubus dengan volume limas yakni:
V sisa = V kubus – V limas
V sisa = 1728 cm3 – 288 cm3
V sisa = 1440 cm3

Nah itu teladan soal cara menghitung volume kubus dan limas. Jika ada hambatan atau permasalahan dalam memahami bahan dan teladan soalnya, silahkan tanyakan di kolom komentar. Kita niscaya bisa.
