What is ∫sin⁡2xdx+∫cos⁡2xdx\int \sin ^2 x d x+\int \cos ^2 x d x equal to? where c is an arbitrary constant.

Options

  1. Ax+c
  2. Bx22+c\frac{x^2}{2}+c
  3. Cx2+cx^2+c
  4. DNone of the above

Correct answer

A. x+c

Step-by-step solution

∫sin⁡2x⋅dx+∫cos⁡2x⋅dx=∫(sin⁡2x+cos⁡2x)⋅dx=∫dx=x+c\begin{aligned} & \int \sin ^2 x \cdot d x+\int \cos ^2 x \cdot d x \\ & =\int\left(\sin ^2 x+\cos ^2 x\right) \cdot d x=\int d x=x+c\end{aligned}
