Is there any way to get an exact solution rather than integration format. I do not know "applyop" command. Please help me for more understanding to use MAPLE. Thanks restart; u(t):=1+sum((-1)^(i)*Heaviside(t-T[i+1]),i=1..n-1)+sum((-1)^(i)*Heaviside(t-T[n+i]),i=1..n): eq:=diff(x(t),t,t)=u(t)/M: ic:=x(0)=0,D(x)(0)=0: dsolve({eq,ic}) assuming T[n+i]>T[i+1]; yoon
format

Please Wait...
