How to solve for tan 2 theta
Webt = π 6 ± 2πk and t = 5π 6 ± 2πk. where k is an integer. How to: Given 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. WebDepending what quadrant the terminal side of the angle lies in, use the equations in the table below to find the reference angle. In quadrant I, θ'=θ. Example: Find tan (240°). θ is already between 0° and 360° 240° lies in quadrant III 240° - 180° = 60°, so the reference angle is 60°
