Unit 12 Trigonometry Homework 2 Answer Key
The answer key for Homework 2 provides detailed solutions to each problem. Below is a breakdown of the solutions:
Problem 1: Solving Trigonometric Equations
Question: Solve the equation \( \sin x = \frac{1}{2} \) for \( 0 \leq x \leq 2\pi \).
Solution: The sine function equals \( \frac{1}{2} \) at \( x = \frac{\pi}{6} \) and \( x = \frac{5\pi}{6} \). Therefore, the solutions are \( x = \frac{\pi}{6} \) and \( x = \frac{5\pi}{6} \).
Problem 2: Proving Trigonometric Identities
Question: Prove that \( \sin^2 x + \cos^2 x = 1 \).
Solution: This is a fundamental trigonometric identity derived from the Pythagorean theorem. Using the relationship \( \sin^2 x + \cos^2 x = 1 \), the identity is proven.
Step-by-Step Problem Solving
Effective problem-solving in trigonometry involves a systematic approach. Follow these steps to tackle any trigonometric problem:
- Read the problem carefully and identify the given information.
