Question

Find the exact value of cos (arcsin (five divided by thirteen)).

Answer 1

Answer:

0.9231

Step-by-step explanation:

To get the exact value of cos(arcsin(5/13)),

First we need to get the value of the trigonometry function in the bracket i.e arcsin5/13.

arcsin 5/13

= arcsin 0.3846

= 22.62°

Then we will take the cos of the resulting value to give the final exact value of the trigonometry function.

= cos (22.62°)

= 0.9231

The exact value of the given trigonometry function is 0.9231

Answer 2

Answer:

0.99

Step-by-step explanation:

cos(arcsin(5/30)) = 0.98601 ≈ 0.99
