Im building a new basic library, the first function define as:
laplace(f,var,var2)=simplify(-lim(intergral(e^(-replace(var2)*t)*z|replace(var)=t,t),t,0))
but it doesnt work with t^a or a^t...

Why simplify(-lim(intgral(e^(-s*t)*t^20,t),t,0)) works but simplify(-lim(intgral(e^(-s*t)*t^21,t),t,0)) not work?
