= –sin(2x), Double angle identity: sin(2x) = 2sin(x)cos(x)  sin x + √3 cos x = 2 sin 2x. (3). (c) Deduce from parts (a) and (b) that sec x + √3   There are a few trigonometric identities which we must learn to identify on sight.

tanx = t Sec^2 x .dx= dt So now it is, 1/ (1-t)^2 .dt This integral is given by 1/1-t and t= tanx So, it is cosx/cosx - sinx.
