Find the Exact Value arcsin(cot((3pi)/4))

$\arcsin (\cot (\frac{3 π}{4}))$

Step 1

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cotangent is negative in the second quadrant.

$\arcsin (- \cot (\frac{π}{4}))$

Step 2

The exact value of $\cot (\frac{π}{4})$ is $1$ .

$\arcsin (- 1 \cdot 1)$

Step 3

Multiply $- 1$ by $1$ .

$\arcsin (- 1)$

Step 4

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

$- \frac{π}{2}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$- \frac{π}{2}$

Decimal Form:

$- 1.57079632 \dots$
