## What is Sinx 2x?

Sin x^2 is the sine of (x-squared),so it is an ordinary sine function. Sin^2 x is sine-squared of x which is a different function from the sine function. i.e. sin^ 30 (sin 30)^2 1/2it is a chain function of sine of x quantity squared, so you would solve sin x first and then take the square.
