Show hintHide hint
Remember to include all lower degree terms.
Question 2.
If f(x) = e^2x, what would you initially guess as a trial solution?
Show hintHide hint
Consider if you need to adjust this solution.
3Question 3.
What is a trial solution?
Show hintHide hint
Think about the role it plays in solving differential equations.
4Question 4.
True or False: The trial solution does not need to be adjusted if it matches part of the complementary function.
