The Functions exp(z), log(z), sin(z) and cos(z) for z ∈ ℂ
In this chapter we extend some of the elementary functions to complex arguments. We recall that we can write a complex number z in the form z = ∣z∣(cos(θ) + i sin(θ)) with θ = arg z the argument of z, and 0 ≤ θ = Arg z < 2π the principal argument of z.
