`U=x^4`, Find ` (du)/dx`

(x^(1/3))^4 , Find dy/dx

If y=log_u|cos4x|+|sinx| ,where u=sec2x find (dy)/(dx) at x=-pi/6

If u=3x^(12) and v=x^(6) then (du)/(dv) is

If u=sin^(-1)((2x)/(1+x^(2)))andv=tan^(-1)((2x)/(1-x^(2))) , then (du)/(dv) is

If variables x and y are related by the equation x=int_(0)^(y)(1)/(sqrt(1+9u^(2))) du, then (dy)/(dx) is equal to

The function u=e^x sin x ; v=e^x cos x satisfy the equation a. v(d u)/(dx)-u(d v)/(dx)=u^2+v^2 b. (d^2u)/(dx^2)=2v c. (d^2v)/(dx^2)=-2u d. (d u)/(dx)+(d v)/(dx)=2v
