Hybrid problem of MFra's two probrems.

[ttokoro]

I think this is the best probrem for electrical engneering students, original from MFra's post.
Try to solve by Mathcad or Prime 9 if you can. 

[ttokoro]

If the values of R and L is below, and the applied voltage is 1 Hz, you can find the answer.
But the conditions are as original ones, Can Prime and Maple solve it or not?

Answer 1.   By using covolution integral for 1 Hz problem.

Hi!
It would be more interesting to determine the response to this signal:

[ttokoro]

The applied voltage waveforms are below and their current responces are made by convolution integral.

[ttokoro]

Answer 2.   By using Laplace convertion for 1 Hz problem.

[ttokoro]

Answer 3. Use convolution to solve the 1 Hz response.

[-MFra-]

Congratulations on the results obtained.

Answer 4. By using Fourier analysys and Laplace transform for from DC to 20th harmonics. 
Below I and V are missed. i(t) is applied voltage and v(t) is transient current responce.

Because I used former RCRC sheet to solve.

Answer 5. By using solve block.
