WebMar 27, 2015 · This seems to be written wrong, there is no real way to solve cos x = 2. If the task were tan ( arccos ( − 2 / 2)) then one knows from the elementary trig values that cos x = − 2 / 2 has the solutions x = ± 135 °, so that arccos ( − 2 / 2) = 3 π 4 and the tangent of that is − 1.

WebFirst, we are taking the arctangent of 2. That is, we are finding some angle 𝜃 such that tan 𝜃 = 2. Then, 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. … WebAnswer (1 of 2): Since I do not want to be solving your problem completely for you, I will just hint at a few helpful formulae to get you going: \sin \left(\alpha + \beta\right) = \sin\alpha \cos\beta + \sin\beta \cos\alpha \sin \alpha = \sqrt{1 - \cos^2 \alpha} \cos \alpha = \sqrt{1 - … WebI have no idea how to actually figure out arcsin, arccos or arctan after watching these three videos.
