Thanks but as the answer suggested I`m using http://www.wolframalpha.com/ but when I input the following integral:

integrate xy^2 dx dy,x=0..y^1/2,y=0..4

The software dosen`t give me the option for step-by-step solution it only gives me the option for related queries which they have the option for step-by-step solution
