Example 21 Find sin Let I1 = sin Hence, we take First function :- = sin Second function :- g = I1 = sin sin I1 = sin cos . Let I2 = cos . Hence, we take First function :- = cos Second function :- g = I2 = cos x (( cos ) ) I2 = cos x ( sin ) I2 = cos x + sin I2 = cos x + 1 Now, Putting value of I2 in (1) , I1 = sin cos I1 = sin cos + 1 I1 = sin cos 1 2I1 = sin cos I1 = 1 2 sin cos + C I1 = 2 sin cos + C I1 = sin cos + sin + 1 I1 = sin cos + sin 1 I1 = sin cos 1 1 2 1 = sin cos 1 I1 = sin cos 2 + 1 2 I1 = ( )+
