Page 1 of 2 14.7 Using Double- and Half-Angle Formulas 877 Solving a Trigonometric Equation Solve tan 2x + tan x = 0 for 0 ≤ x < 2π. SOLUTION tan 2x + tan x = 0 Write original equation.... Half-angle formulas are the better option when you need to find the trig values for any angle that can be expressed as half of another angle on the unit circle. For example, to evaluate a trig function of pi/8, you can apply the half-angle formula to pi/4. Because no combination of sums or differences of special angles gets you pi/8, you know to use a half-angle formula.

The double and half angle formulas can be used to find the values of unknown trig functions. For example, you might not know the sine of 15 degrees, but by using the half angle formula for sine, you can figure it out based on the commonly known value of sin(30) = 1/2. rangle io angular 2 pdf 2 3 3 3 3 4 4 4 5 5 5 5 5 6 6 7 7 7 7 8 8 8 9 9 9 9 Table of Contents Table of Contents Unit 1 - Rational, Exponential, and Logarithmic Functions 5.6 - Rational Functions
