What is the derivative of y=(tan(2x)cos(x))^{3x} ,with respect to ‘x’?

A

dy/dx = ln(tan(x)cos(x))(tan(2x)cos(x))^{3x}

B

dy/dx = -9ln(cos(2x)sec^{2}(x))(tan(2x)cos(x))^{2x}

C

dy/dx = 3ln(tan(2x)cos(x))(tan(2x)cos(x))^{3x}

D

dy/dx = -3ln(tan(x)cos(x))(tan(x)cos(x))^{x}

E

dy/dx = e^{x}(tan(2x)cos(x))(tan(2x)cos(x))^{3x}
