Calculus (Derivatives)

posted by .

Using the product rule, find the derivative of the following function:
(x^1/2 cscx sinx).

  • Calculus (Derivatives) -

    First off, csc * sin = 1
    So, y = √x

    However, if you insist on doing it the hard way

    y = √x cscx sinx
    y' = 1/2√x cscx sinx + √x(cscx sinx)'
    = 1/2√x * 1 + √x(-cscx ctnx * sinx + cscx cosx)
    = 1/2√x + √x(-ctnx + ctnx)
    = 1/2√x
