SUMMARY

The discussion centers on the equivalence of two solutions for an inverse Laplace transform problem involving complex equations and partial fractions. The user's solution is expressed as -2i+1exp((1-i)*t) + -2i+1exp((1+i)*t), while the book's answer is 2exp(t)cos(t) + 3exp(t)sin(t). The user seeks to convert the book's answer into exponential functions to facilitate comparison. The Euler's formula, ejθ = cos θ + j sin θ, is suggested as a method for this conversion.

I'm doing lapace transforms and I'm to the stage where I am finding inverse transforms. A problem I am stuck on involves doing partial fractions of a complex equation. I have attempted to do it, and now I have a question about my answer.

My answer is

-2i+1exp((1-i)*t) + -2i+1exp((1+i)*t)

Books answer

2exp(t)cos(t)+3exp(t)sin(t)

Is my answer equivalent?

Can you convert the book's answer into exp functions (no trig)? Then they should be easy to compare.
