Find an angle between 0 and 2π that is coterminal with the given angle

(-13pi)/(3) (15pi)/(9)-For -13pi/3, add 2pi until you get what you want.2pi= 6pi/3 -13pi/3+18pi/3= 5pi/3 15pi/9 is between 0 and 2pi already.2pi=18pi/9 0 Hoping this helps!

Partial Fractions Integration

I generally understand partial fractions, but this problem is a little more complex.Ive tried it a few different ways, and Im still stuck. I need to integrate (7x^2 + 2x - 4) / (x^3 + 2x^2) Thank yo

Why is the derivative of the inverse sin(x) equal to 1/sqrt(1-x^2)

lets say y=inv sin(x) when we implicitly differentiate both sides we can come to the conclusion that dy/dx=1/cos(y) so why is the formal derivative of the inverse sine equal to 1/sqrt(1-x^2) ? how is

Factor the expression 4x^2-32xy+64y^2 into product of binomials.

4x^2 - 32xy + 64y^2 = (2x - 8y)^2, or (2x - 8y) * (2x - 8y)-4x^2-32xy+64y^2 = 4(x^2-8xy+16y^2) = 4(x-4y)^2

For graph of function defined by y=x^3-6x, find the coordinates of the points which the gradient is 6

I was wondering how you would do this question. Thank You-From y = x^3 - 6x, first find the gradient function: y = 3x^2 - 6 Now, the gradient given is 6, so we need to find x such that: 3x^2 - 6 =
