For which angle θ is cos θ −1 270°
Did you know?
WebThen, after finding that angle, we are taking the sine of that angle! In other words, if we have an angle 𝜃 such that tan 𝜃 = 2, we must find sin 𝜃. This is possible to do with a right triangle. If 𝜃 is an angle in a right triangle such that the opposite side is 2 and the adjacent side is 1, … WebThe following angles are drawn in standard position: 1. θ=40D 2. 160θ= D 3. θ=−320D Exercises Sketch each of the following angles in standard position. (Do not use a protractor; just draw a brief sketch.) 1. 120θ= D 2. 45θ=− D 3. 130θ=− D 4. θ=270D θ=−90D 6. θ=750D x y θ Notice that the terminal sides in examples
WebJul 12, 2024 · cos θ = -1 at θ= 180°. Since, cos θ has a period of 2π, or 360°. It means that cos θ will have the value equal to -1 again after an interval of 2π. Thus, cos θ will be -1 … WebSolve your math problems using our free math solver with step-by-step solutions.
