Webcos⁻¹(cos(θ)) = cos⁻¹((19/20) So in the LHS we take the cosine of theta, and then take the inverse cosine, which is just theta, so we have θ = cos⁻¹((19/20). Also be aware that there are alternative names for the inverse trigonometric functions: cos⁻¹ is also called arcosine, sin⁻¹ is arcsine, and tan⁻¹ is arctangent. WebA trigonometric equation - Finding the value of theta. I have to find the value of θ in this equation " cos 2 θ sin θ = 1 ". 4 sin 2 θ − 1 = 0 sin 2 θ = 0.25 sin θ = + 0.5, − 0.5 θ = 30, 150, 210, 330. But for " cos 2 θ sin θ = 1 ", I figured, according to the fact that cos α can be only between -1 and 1. And the same for sin α ...
