kindly answer all step by step please

Autnor: Objective: The goal of this assignment is to get used to scientific computing using python and its libraries. So, do not make the calculations by hand. Suggestion: Follow the lecture notes in GitHub Consider the following function s(t)=2etcos(2t). Using sympy (or numpy or scipy), do the following tasks - Define the function. - ds/dt In [ ] - s(t)dt - Plot the three signals together. - Fourier tranform of S(w)=F{s(t)u(t)}, where u(t) is the step function. In [] : - Plot the real part of S(w),5w5 - Plot the imaginary part of S(w),5w5 In [ ] : - Plot the absolute value of S(w),5w5 In [ ] - Plot the phase of S(w),5w5 In [ ]
