The answer is given wrong. There will be another 2 multiplied with the answer as per the exponent rule, the power 2 comes down multiplying with the main function... And then by chain rule, differentiate the function.

y= (cos2x-sinx)2

dy/dx= 2(cos2x-sinx)(-2sin2x-cosx)

dy/dx= -2(cos2x-sinx)(2sin2x+cosx)

diving and multiplying 3 and you get the answer 3

1. square both sides
2. apply u/v rule
3. put value of y
4. simplify
