How to solve a trigonometric equation
WebThe first solution is 45° more than a multiple of 180°, so (180n)° + 45° should do. The second solution is 30° more than a multiple of 180° and (because of the "plus / minus") also 30° less than that same multiple, so (180n)° ± 30° will cover this part. x = (180n)° ± 30°, (180n)° + 45° for all integers n Content Continues Below Solve WebLook for a pattern that suggests an algebraic property, such as the difference of squares or a factoring opportunity.

How to solve a trigonometric equation
Did you know?
WebThe first trig equation, cos (α) = \frac {1} {2} 21, gives me α = 60° and α = 300°. The second equation gives me α = 180°. So my complete solution is: α = 60°, 180°, 300° Solve sin (β) = sin (2β) on the interval 0° ≤ β < 360° I can use a double-angle identity on the right-hand side, and rearrange and simplify; then I'll factor: WebDec 20, 2024 · Solve the equation exactly: 2cosθ − 3 = − 5, 0 ≤ θ < 2π. Solution Use algebraic techniques to solve the equation. 2cosθ − 3 = − 5 2cosθ = − 2 cosθ = − 1 θ = π Exercise 7.5.2 Solve exactly the following linear equation on the interval [0, 2π): 2sinx + 1 = 0.
