Give the exact value of the expression without using a calculator.

sine left parenthesis 2 tangent Superscript negative 1 Baseline eight fifteenths right parenthesis

.

Step-by-step explanation:

To find the exact value of the expression

First, we need to simplify the expression .

Draw a triangle in the plane with vertices , , and the origin. Then is the angle between the positive x-axis and the ray beginning at the origin and passing through .

Therefore,

Now, use the identity

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|

do your own work and don"t cheat.
