Evaluate the following trigonometric expression, using the principal value for the cosine tan(Cos-1(-1/2))

Given:

The expression is

To find:

The value of given expression.

Solution:

We have,

Therefore, the value of given expression is .

its c or d   take a lucky guess my dude

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
