Solving Difference Equation and Differential Equation
1. Complex Exponentials: Simply the following expression and give your answer both in polar and rectangular form.
o c=3ejπ/4+4e−jπ/2
2. Difference Equations: Solve the following difference equation using recursion by hand (for n=0 to n=4)
o y[n] + 0.5y[n-1] = 2x[n-1]; x[n] = δ[n], y[-1] = 0
3. Differential Equations: Solve the following problem for y(t).
o dy/dt + 2y(t) = 2x(t); x(t) = u(t), y(0) = −1
The solution gives detailed steps on solving difference equation, solving differential equation and simplifying complex exponential in polar and rectangular form.
A) Solve the following differentialequation by as many different methods as you can.
(See attachment for equation)
b) There is a type of differentialequation which will always be solvable by two different methods. What type of differentialequation is it and which other method can always be used to solve it?

I already solved the homogeneous portion, and I need help solving the particular solution and of course combining the two to get the entire solution to the differentialequation. Not too difficult - see attachment. Please use equation editor if possible. Thank you.
