Step 2.3.2.1

Move $t^{2}$ out of the denominator by raising it to the $- 1$ power.

$s + C_{1} = \int {(t^{2})}^{- 1} d t + \int \cos (t) d t$

Step 2.3.2.2

Multiply the exponents in ${(t^{2})}^{- 1}$ .

Step 2.3.2.2.1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$s + C_{1} = \int t^{2 \cdot - 1} d t + \int \cos (t) d t$

Step 2.3.2.2.2

Multiply $2$ by $- 1$ .

$s + C_{1} = \int t^{- 2} d t + \int \cos (t) d t$

Step 2.3.3

By the Power Rule, the integral of $t^{- 2}$ with respect to $t$ is $- t^{- 1}$ .

$s + C_{1} = - t^{- 1} + C_{2} + \int \cos (t) d t$

Step 2.3.4

The integral of $\cos (t)$ with respect to $t$ is $\sin (t)$ .

$s + C_{1} = - t^{- 1} + C_{2} + \sin (t) + C_{3}$

Step 2.3.5

Simplify.

$s + C_{1} = - \frac{1}{t} + \sin (t) + C_{4}$

Step 2.4

Group the constant of integration on the right side as $K$ .

$s = - \frac{1}{t} + \sin (t) + K$
