Hi,

Please help me on this. I do not how to start on this integration, so i simply apply basic integration rule. Usually, there is a formulas sheet for me to convert this alike question to trigo form(after integrate) but this one seem different.

edited: y^2 is const

Use the substitution u=x^2+y^2.

sorry there is an edit.
 


It was already clear that y is a constant. Post 2 still holds.
