Question statement

Having found the partial fraction breakdown:

$X(s)=\frac{\var{A}}{s+\var{a1}}+\frac{\var{B}s+\var{C}}{s^2+\simplify{{b1}*2}s+\var{c1}}$

Give any introductory information the student needs.

Ask the student a question, and give any hints about how they should answer this part.

Write down the inverse Laplace transform

$x(t)=$ Unnamed gap

Advice

$X(s)=\frac{\var{A}}{s+\var{a1}}+\frac{\var{B}s+\var{C}}{s^2+\simplify{{b1}*2}s+\var{c1}}$

$X(s)=\frac{\var{A}}{s+\var{a1}}+\frac{\var{B}s+\var{C}}{(s+\var{b1})^2+\simplify{{c1}-{b1}^2}}$

$X(s)=\frac{\var{A}}{s+\var{a1}}+\frac{\var{B}(s+\var{b1})-\simplify{{B}*{b1}-{C}}}{(s+\var{b1})^2+\simplify{{c1}-{b1}^2}}$

$x(t)=\var{A}e^{\var{a1}t}+\var{B}e^{-\var{b1}t}cos\left(\sqrt{\simplify{{c1}-{b1}^2}}t\right)+\frac{-\simplify{{B}*{b1}-{C}}}{\sqrt{\simplify{{c1}-{b1}^2}}}e^{-\var{b1}t}sin\left(\sqrt{\simplify{{c1}-{b1}^2}}t\right)$
