∫01sin⁡(3x+2) dx\int\limits_{0}^{1} \sin{\left(3 x + 2 \right)}\, dx 
Integral(sin(3*x + 2), (x, 0, 1))
Detail solution

  1. Let u=3x+2u = 3 x + 2.

    Then let du=3dxdu = 3 dx and substitute du3\frac{du}{3}:

    ∫sin⁡(u)3 du\int \frac{\sin{\left(u \right)}}{3}\, du

    1. The integral of a constant times a function is the constant times the integral of the function:

      ∫sin⁡(u) du=∫sin⁡(u) du3\int \sin{\left(u \right)}\, du = \frac{\int \sin{\left(u \right)}\, du}{3}

      1. The integral of sine is negative cosine:

        ∫sin⁡(u) du=−cos⁡(u)\int \sin{\left(u \right)}\, du = - \cos{\left(u \right)}

      So, the result is: −cos⁡(u)3- \frac{\cos{\left(u \right)}}{3}

    Now substitute uu back in:

    −cos⁡(3x+2)3- \frac{\cos{\left(3 x + 2 \right)}}{3}

  2. Now simplify:

    −cos⁡(3x+2)3- \frac{\cos{\left(3 x + 2 \right)}}{3}

  3. Add the constant of integration:

    −cos⁡(3x+2)3+constant- \frac{\cos{\left(3 x + 2 \right)}}{3}+ \mathrm{constant}

The answer is:

−cos⁡(3x+2)3+constant- \frac{\cos{\left(3 x + 2 \right)}}{3}+ \mathrm{constant}
