The values of six trigonometric functions using
Answer to Problem 10E
Explanation of Solution
Given:
The values of expressions,
Concept Used:
- Reciprocal identities of trigonometric functions:
- Quotient Identities:
- In Quadrant I, all trigonometric functions are positive.
- In Quadrant II, only sine and cosecant are positive.
- In Quadrant III, only tangent and cotangent are positive.
- In Quadrant IV, only cosine and secant are positive.
Calculation:
In order tofind the values of the six trigonometric functions, use the reciprocal and quotient identities of trigonometric functions.
Using the reciprocal and quotient identities, it gives
Thus, the values of the six trigonometric function is given by,
