Correct Answer

Explanation

To evaluate the integral ∫sin(2x) dx, we can use the integration formula for the sine function:∫sin(u) du = -cos(u) + CIn this case, u = 2x, so we have:∫sin(2x) dx = -cos(2x) + CTherefore, the integral of sin(2x) with respect to x is -cos(2x) plus a constant of integration, C.
