A phasor plot represents this function in a complex plane, and this function also appears in the Fourier and Laplace transforms.
A phasor plot represents this function in a complex plane, and this function also appears in the Fourier and Laplace transforms. It is equal to the sum of the hyperbolic sine and hyperbolic cosine. Euler's formula states that this function of i theta equals cis theta. This function, the only nonzero one to equal its own derivative, is often used in problems involving radioactive decay and compound interest. For 10 points, name this inverse of the natural logarithm, which involves a base e being raised to a power.
