area anikalo bhaiyon...

clearly x and y range from -1 to 1

x² + y² = 1

area of circle is ∩

i think we shud start by substitution e.g
in case of x, t= cos 2z
in case of y, t= tan z
adjust the limits of t in both cases which may help in finding out the integration of the area.

@eureka, u hv done any mistake in taking limits, i suppose!!!
correct me if i am wrong!!!

limits theek hain bhai..
