Question

Dervative Calculus:

y = (1+ cot x) *2

y = cot ( pi - 1/x )

y = tan ( cot x )

y = csc ( pi - 2x )

y = cos 2 x - 5 cot 3 x


Find y dash, or dy/dx (derivative)


Thanks in advance!

Answer 1

1...y=(1+cot x)*2
y'=(-2cosec^2x)
3...sec^2 (cot x)

Answer 2

y== cot ( pi - 1/x ) find the derivative in chain rule
