Dear student
Q1 Solution : Sin^-1(SinX) = X
So, It will be Simplified to Integral (X) from (-pie/2 to pie)
[X^2 / 2 ] limit from – pie /2 to pie
Ans = pie^2 / 4
= 2.50
Please ask one question in a thread,
Good Luck

once again, vikas’s answer is full of crap. correct method is as follows:
note that sin-1(sinx)= x for x belonging to – pi/2 to pi/2 and pi – x for x belonging to pi/2 to pi.
so, break the integral as
∫xdx from – pi/2 to pi/2 + ∫pi – x from x belonging to pi/2 to pi.
= 0 + pi*pi/2 – ½ *3pi^2/4
= (pi^2/2)*(1 – 3/4)
= pi^2/8, approx 1.2337
kindly approve :=)
