What is Heaviside's method?
- 5.4 Heaviside’s Method This practical method was popularized by the English electrical engineer Oliver Heaviside (1850–1925). A typical application of the method is to solve 2s (s+1)(s2+1) = L(f(t)) for the t-expression f(t) = ?e?t+cost+sint. The details in Heaviside’s method involve a sequence of easy-to-learn college algebra steps.
