How do you solve trigonometric equations that involve multiple angles, such as 2sin(x)cos(x) = sin(x), within the interval [0, 2π]?

by zhanhongyuan | Jan 22, 2025 | Math

Home ”How Answer 1 Holly Jones PhD To solve 2sin(x)cos(x) = sin(x) within [0, 2π], first use the identity 2sin(x)cos(x) = sin(2x). The equation becomes sin(2x) = sin(x). This implies two cases: 2x = x + 2kπ or 2x = π – x + 2kπ. Solving these gives x = 0,...
