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). WebOther fourth roots are. w = 2 (cos 0 + 2 π 4 + i sin 0 + 2 π 4) = 2 (cos π 2 + i sin ... Consider the length of the graph of f(x) = 5/x from (1, 5) to (5, 1).
