From the unit circle we see that sin x and cos x can only have the same value in two places, in x = ... sinx = cosx tanx = 2t. 1+t2 . Write I = / a. 0 dx. 1+cosx+sinx . Since dt/dx = sec2. (x/2). 2. = (1+t. 2. )/2, we see that. I = ∫ tan(a/2). Dec 3, 2015 ... cosx/1+sinx + 1+sinx/cosx = 2sec I'd like to know how to solve this problem We are learning trigonometric identities. Given the trigonometric identity as It can be verified by expanding and simplifying the left hand side as follows. May 30, 2016 ... sin(x + x) = sin(2x) = sin(x)cos(x) + cos(x)sin(x) = 2sin(x)cos(x) Therefore, sin(x)cos(x) = (1/2) Asmander: sinx=1−sinx 2sinx=1. 1. sinx= 2. π, 5π. x= + 2kπ v x= + 2kπ. 6, 6 · Janek191: rysunek sin x = cos x. π. x = + π*k , k − dowolna liczba całkowita. 4 ...
