Theta triangle
WebProof: To prove the triple-angle identities, we can write \sin 3 \theta sin3θ as \sin (2 \theta + \theta) sin(2θ+θ). Then we can use the sum formula and the double-angle identities to get … WebLooking at the triangle, the side opposite the angle theta has a length of 2 while the side adjacent has a length of 1. Further, the hypotenuse has a length of \(\sqrt{5}\). This is all that is needed to calculate the values of all the trig functions. So, start plugging them in …
