    1. The problem statement, all variables and given/known data
    find dy/dx at x=-1 .


    2. Relevant equations
    sin ysin pi*x/2 + 31/2/2(sec-12x) +2x(tan(ln(x+2)))=0


    3. The attempt at a solution
    There is coming a term ln(sin pi*x/2) during differentiation which will be a ln of a negative number. Sorry if the problem is too easy .I am just starting differentiation.

    Re: Differentiation

    Is that really [tex]\sin (y^\frac{sin \pi x}{2})[/tex]?
