Hi,

Q1. Evaluate the following integrals by suing the given substitution.

a) f [ {e^squareroot(x)}/{2*squareroot(x)} ], u =squareroot(x)

b) f { x*sin(x^2) } dx, substitution u = x^2

c) f (2x+5)/(x^2 + 5x + 17), substitution u = x^2 + 5x +17

(*note: the functions above are antiderivatives...)

can anyone help me with these questions? im clueless - steps and answers would be appreciated...

thanks,

moon
