/ //sin(a*x + b) \ | ||------------ for a != 0| | cos(a*x + b) dx = C + |< a | | || | / \\ sin(b) otherwise /
$$\int \cos{\left(a x + b \right)}\, dx = C + \begin{cases} \frac{\sin{\left(a x + b \right)}}{a} & \text{for}\: a \neq 0 \\\sin{\left(b \right)} & \text{otherwise} \end{cases}$$

/sin(a + b) sin(b) |---------- - ------ for And(a > -oo, a < oo, a != 0) < a a | \ cos(b) otherwise
$$\begin{cases} - \frac{\sin{\left(b \right)}}{a} + \frac{\sin{\left(a + b \right)}}{a} & \text{for}\: a > -\infty \wedge a < \infty \wedge a \neq 0 \\\cos{\left(b \right)} & \text{otherwise} \end{cases}$$
