Math Problem Statement
cot x = -12 how to find the values
Solution
To solve the equation , we need to express in terms of trigonometric functions we are more familiar with.
Step 1: Recall the cotangent identity
The cotangent function is the reciprocal of the tangent function, so: Thus, the equation becomes: This simplifies to:
Step 2: Find the angle
To find , we take the inverse tangent (or arctangent) of . In other words: Using a calculator:
Step 3: Find all possible solutions
Since the tangent function is periodic with a period of radians (or 180°), the general solution for will be: x = -4.76^\circ + 180^\circ n \quad \text{(for any integer n)} or in radians: x = -0.083 \, \text{radians} + \pi n \quad \text{(for any integer n)}
Final Answer:
The values of that satisfy are approximately: x \approx -4.76^\circ + 180^\circ n \quad \text{(for any integer n)} or x \approx -0.083 \, \text{radians} + \pi n \quad \text{(for any integer n)}
