Question

Please work out the step-by-step process of how you get to the solution on paper, please. The answer is given, I just want to see the work done that teaches how to get the solution. *See Image.

Substituting these expressions into the system shown earlier yields the following system.

\[
(\cos 5t)v_1' + (\sin 5t)v_2' = 0
\]

\[
(-5 \sin 5t)v_1' + (5 \cos 5t)v_2' = 4 \sec 5t
\]

Solve this system for \( v_1'(t) \) and \( v_2'(t) \).

\[
v_1'(t) = -\frac{4}{5} \tan 5t
\]

\[
v_2'(t) = \frac{4}{5}
\]

I don't know if you know this, but when you upload your work it gets all jumbled together and makes it unreadable. That's why I asked for a worked solution on paper. Please resubmit.
