Please help!! Thank you very much.
Hi plato,

Could you please show me the full steps ? Thank you very much.
Hi Krizalid,
Please show me the full steps with trig substitution. I still can't work to the end with it. I really forgot the trig substitution work .
The previous question. I worked it out simply by using the face that the integral is equal to 1/2 pi a^2 .
