How do you differentiate f(x) =sin(3x-2)* cos(3x -2) ? Calculus Differentiating Trigonometric Functions Differentiating Inverse Trigonometric Functions 1 Answer Konstantinos Michailidis Apr 4, 2016 Remember that sin2A=2*sinA*cosA Hence f(x)=sin(3x-2)*cos(3x-2)=>f(x)=1/2*sin(2*(3x-2)) Hence (df)/dx=1/2*cos(2(3x-2))*6=3*cos(6x-4)= Finally f'(x)=3*cos(6x-4) Answer link Related questions What is the derivative of f(x)=sin^-1(x) ?
