Why do people do this?

because [math]E_k = \frac{1}{2}mv^2[/math]

Because he's a cunt.. Who is trying to open your mind and ignite it to greater feats than you ever imagined. Look back on this in 4 years and see how it helped. He will still be a cunt though

Is this math course trigonometry?
>>
>>8233098
It's just different units, which could make subsequent calculations more convenient (if you're programming).

Can you guys help a retard? Trying to learn all my high school math again, feel motivated but reached this kinda problem when trying to foil. What do I do about the exponents outside the parenthesis?
>>
>>8233098
ln(x) + 2 * ln(y) - 9 * ln(z)
or
ln(x) + ln(y^2) - ln(z^9)
>>
>>8234115
multiply what's inside the parenthesis by the outer exponent
>>
>>8234115
Multiply the exponents in parentheses by the exponent out of parentheses, square the -5 and cube the 2.
>>
>>8234115
(25w^6x^4)(8w^15)
200w21x^4
Serach up properties of exponents.
>>
>>8234098
Yes

It's weird if he gave you that formula and told you it was the one for a circle when in reality it's a generalization of the area of a part of a circle. But I mean it's right because that's what the integral used to derive the area formula would come to if you used and indefinite integral for the angle.
Tl;dr he's just kind of being a dick
