WebSo the sine of theta-- the sine of this angle is equal to the opposite over the hypotenuse. The hypotenuse is 1, has length 1 because these are the standard basis vectors. So this is equal to the sine of theta. Now, this distance is equal to the sine of theta that's going in the negative direction, so it's going to be equal to the minus sine of ... WebLearn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°. We want to prove that the sine of an angle equals the cosine of its complement. \sin (\theta) = \cos (90^\circ-\theta) sin(θ) = cos(90∘ … terbacil https://branderdesignstudio.com
