I-Cal I / Video 2 (4 to 6) Integral Calculus I - Integrals sin^2 x, sec x tan x, 1/sq.r(1 - x^2)

I-Cal I / Video 2 (4 to 6)
We have six ratios sin^2 x, cos^2 x, ........... But here we discuss only two integrals sec^2 x and cosec^2 x
similarly, integrals sec x tan x and cosec x. cot x and 1/sq.rt ( 1-x^2) ..etc are discussed here.
Try to remember these results by comparing with the corresponding results in Differentiation calculus.
