Hello guys I need to solve an easy derivative but I think I need to re-write my function.The function is f(x)=sin2x,is it correct if I re-write the function as f(x)=sinx+x?Thank you for your time.

That depends upon what you mean. "sine" is a function and should always be written, for clarity, with parentheses: sin(2x), not "sin2x". That is not a problem with "sin2x" since you clearly (I hope!) don't mean "sin(2) times x". It is, however, a problem with "sinx+ x". sin(2x) is equal to sin(x+ x). It is NOT equal to sin(x)+ x.
