The nth derivative of sin 2x can be defined as follows using this trend: (sin 2x) (n) = (sin 2x) (n) = (sin 2x) (n) If n is a multiple of 4, 2n sin 2x; if n is less than a multiple of 4, -2n cos 2x. If n is 2 less than a multiple of 4, then -2n sin 2x.

Webf(x)=sin2x−cos2x On differentiating both sides w.r.t x, we get f(x)=cos2x×(2)−(−sin2x)×(2) f(x)=2(cos2x+sin2x) Put x= 6π Therefore, f(6π)=2(cos 3π+sin 3π) f(6π)=2(21+ 2 3) f(6π)=2( 21+ 3) f(6π)=1+ 3 Hence, the value is 1+ 3.
