To find: the exact value of the trigonometric expression when
Answer to Problem 44E
Explanation of Solution
Given information:
Given expression,
Calculation:
Consider that
The sine of an angle is equal to opposite side over the hypotenuse. Since
Since tangentof an angle is equal to opposite side to the adjacent side.
Therefore:
Since,
The tangent of an angle is equal to opposite side to the adjacent side therefore:
Apply the sum formula for tangent that is:
Substitute:
So,
Therefore,
