Rewrite the integrand:

$\sin^{25}{\left(x \right)} = \left(1 - \cos^{2}{\left(x \right)}\right)^{12} \sin{\left(x \right)}$
There are multiple ways to do this integral.
Method #1
1. Rewrite the integrand:
  
  $\left(1 - \cos^{2}{\left(x \right)}\right)^{12} \sin{\left(x \right)} = \sin{\left(x \right)} \cos^{24}{\left(x \right)} - 12 \sin{\left(x \right)} \cos^{22}{\left(x \right)} + 66 \sin{\left(x \right)} \cos^{20}{\left(x \right)} - 220 \sin{\left(x \right)} \cos^{18}{\left(x \right)} + 495 \sin{\left(x \right)} \cos^{16}{\left(x \right)} - 792 \sin{\left(x \right)} \cos^{14}{\left(x \right)} + 924 \sin{\left(x \right)} \cos^{12}{\left(x \right)} - 792 \sin{\left(x \right)} \cos^{10}{\left(x \right)} + 495 \sin{\left(x \right)} \cos^{8}{\left(x \right)} - 220 \sin{\left(x \right)} \cos^{6}{\left(x \right)} + 66 \sin{\left(x \right)} \cos^{4}{\left(x \right)} - 12 \sin{\left(x \right)} \cos^{2}{\left(x \right)} + \sin{\left(x \right)}$
2. Integrate term-by-term:
  1. Let $u = \cos{\left(x \right)}$ .
    
    Then let $du = - \sin{\left(x \right)} dx$ and substitute $- du$ :
    
    $\int u^{24}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:

      So, the result is: $- \frac{u^{25}}{25}$
    Now substitute $u$ back in:
    
    $- \frac{\cos^{25}{\left(x \right)}}{25}$
