    Challenging Indefinite Integral e^arccos x

    Homework Statement Integrate: ((e^arccos(x))(dx))/(sqrt(1-x^2)) Image of the question is attached. Homework Equations The Attempt at a Solution I think i took the right first step for substitution: u=arccos(x); cos(u)=x; (du)(-sin(u))=dx Substituting u into the...
