Find y′ if x^(3y) = y^(2x). 1. y′= 3y^2(ln x − 1) 3y ln x + 2x 2. y′ = y^2(ln x − 1) ...

Find the derivative of f(x) = sqrt(36-x^2) / 9x when x=2

Pretty straight forward, but i am having trouble. You help would be much appreciated

If y= 1+cosx/sinx , show that dy/dx=1/cosx-1

Please help me differentiates this.
