Math Problem Statement
cot pheta = 24/7 and sin pheta is less than 0, find the 5 remaining trig functions
Solution
To find the remaining trigonometric functions, let's first analyze the given information:
Step 1: Understand the quadrant
- . Since cotangent is positive, and sine is negative (), the angle is in the third quadrant, where both sine and cosine are negative.
Step 2: Relation between cotangent and tangent
Step 3: Use the Pythagorean identity to find the hypotenuse
Using the relation , we construct a right triangle with:
- Adjacent side = 24
- Opposite side = 7
The hypotenuse is given by:
Step 4: Determine all trigonometric functions
Now we compute the six trigonometric functions:
- (negative in the third quadrant).
- (negative in the third quadrant).
- .
- .
- .
- .
Final Answer:
Do you want me to provide a step-by-step explanation for any specific part?
Here are 5 related questions for further exploration:
