x=0. Mar 27, 2011 · Simplify the LHS by first getting a common denominator of sin(x)*(1 + cos(x)). LHS becomes: [(1 + cos(x)) - sin²(x)]/[sin(x)*(1 + cos(x))] = [(1 + cos(x)) - (1 - cos²(x))]/[sin(x)*(1 + cos(x))] = [cos(x) + cos²(x)]/[sin(x)*(1 + cos(x))] = cos(x)(1 + cos(x))/[sin(x)*(1 + cos(x))] = cos(x)/sin(x) = cot(x) Feb 17, 2008 · The denominator is a difference of squares, so you get 1-sin^2 x. what you have now is.

So the only solutions are x=pi, x=3pi/2.

Overiť totožnosť. 1-sinx cosx = cosx 1 + sinx

You know that 1-sin^2x is equal to cos^2x. so know you have. cosx(1+sinx) / cos^2x. get rid of the cosx on top by simplifying and the cos^2x so that you're left with (1+sinx) / cos x.
