To calculate: The value of trigonometric ratios if
Answer to Problem 21E
The value of trigonometric ratios are,
Explanation of Solution
Given information:
The value of trigonometric function
Formula used:
The trigonometric ratios for a right angle triangle are defined as,
Calculation:
Consider the provided value of trigonometric function
Since, the cotangent function is expressed as
The figure obtained is provided below,
Observe that adjacent side is 1 unit and opposite is 1 unit.
Now, let the length of hypotenuse be x , as it is a right angle triangle so,
Therefore, length of hypotenuse is
Recall that the trigonometric ratios for a right angle triangle are defined as,
Apply it, to estimate the value of trigonometric ratios,
The value of sine function is,
The value of cosine function is,
The value of tangent function is,
The value of cosecant function is,
The value of secant function is,
The value of cotangent function is,
Hence, the value of trigonometric ratios are,
