The output is displayed as syntax error for the question ilaplace(4/sˆ3,s,t).Tried a lot but couldn't figure it out.Please help.
Your "ˆ" is wrong. Should be "^". Try ilaplace(4/s^3,s,t)

Hi Guys! Please can someone help me plot JUST THE REAL (not imaginary) part of this two differential equations, here is my code? Thank you.
Use the |real| function. fplot(real(I_1Sol)) Does this give the expected plot? Karan.
