WebTo prove sin x/1-cos x = cosec x + cot x We know that, Sin^2 x = 1- cos^2 So from RHS we get, Cosec x+cot x =1/sin x + cos x/sin x So taking LCM, We get, 1+cos x/sin x Now multiply both numerator and denominator by sin x to get denominator as sin^2 x We get, (1+cos x)(sin x)/sin^2 x Now we can write sin^2 x as 1- cos^2 x So, we get (1+cos x ...
