Solving Trigonometric Equations By Finding All Solutions
WebGiven a trigonometric equation, solve using algebra. Look for a pattern that suggests an algebraic property, such as the difference of squares or a factoring opportunity. Substitute the trigonometric expression with a single variable, such as x or u. Solve the equation the same way an algebraic equation would be solved. WebDec 20, 2024 · To define the trigonometric functions, first consider the unit circle centered at the origin and a point P = (x, y) on the unit circle. Let θ be an angle with an initial side that lies along the positive x -axis and with a terminal side that is the line segment OP. An angle in this position is said to be in standard position (Figure 1.7.2 ). WebJun 13, 2024 · Solving trigonometric equations - from the basics to more challenging problems.
