Question

Find the exact value of each expression, if it is defined. Express your answer in radians. (If an answer is undefined, enter UNDEFINED.)
(a) sin−1(-squareroot of 2/2)
(b) cos−1(-squareroot of 2/2)

Answer 1

Answer:

a) -0.7854

b) 2.36

Step-by-step explanation:

Here, we want to find the value of the angles in radians

We proceed as follows;

a) arcsin( - √2/2)

= -0.7854

b) arccos(-√(2)/2

= 2.36
