WebWe have previously used the properties of equilateral triangles to demonstrate that sin π 6 = 1 2 sin π 6 = 1 2 and cos π 6 = 3 2. cos π 6 = 3 2. We can use these values and the definitions of tangent, secant, cosecant, and cotangent as functions of sine and cosine to find the remaining function values. Web= cos(θ)−isin(θ) where the second step comes from the parity (even/odd-ness) of the sin and cos functions, which was given in the hint. Now all we have to do is either add or subtract the functions. If we add them, we ﬁnd eiθ +e−iθ = (cos(θ)+isin(θ))+(cos(θ)−isin(θ)) = 2cos(θ) From that, we get 1 2 eiθ +e−iθ = cos(θ).

Webeiθ +e−iθ = (cos(θ)+isin(θ))+(cos(θ)−isin(θ)) = 2cos(θ) From that, we get 1 2 eiθ +e−iθ = cos(θ). On the other hand, if we subtract them, we ﬁnd eiθ −e−iθ = … WebQuestion: Consider the following.
