Question

Need help with differentiation
I'll post the pic in a bit

Answer 1

With # 1 &3

Answer 2

I already did 1a

Answer 3

Okay, so you know how to do implicit if you did 1a, lol.

Answer 4

So is it part b thats the trouble or what?

Answer 5

B&c
And fractions for#3

Answer 6

well, b just means solve for y and then differentiate. So basically get y by itself. So
9x^2 - y^2 = 1
9x^2 -1 = y^2

y = sqrt(9x^2-1) So now we just differentiate that. Its a chain rule, so we just do the power rule with the sqrt (1/2 exponent) and multiply it by the derivative of the inner portion, 9x^2-1. So that gives us:


Did you get anything like that for 1a?
