Find the Exact Value cot(pi/2)-sin(pi/2)

$\cot (\frac{π}{2}) - \sin (\frac{π}{2})$

Step 1

Simplify each term.

The exact value of $\cot (\frac{π}{2})$ is $0$ .

$0 - \sin (\frac{π}{2})$

The exact value of $\sin (\frac{π}{2})$ is $1$ .

$0 - 1 \cdot 1$

Multiply $- 1$ by $1$ .

$0 - 1$

Step 2

Subtract $1$ from $0$ .

$- 1$
