OpenLab assignment: crowd-sourced Test #1 solutions

Due Monday, March 13

Grampa simpson bursting through the door saying, "I got the answer!"

Step 1

Choose one of the questions from Test #1 that you did not receive full credit for and re-solve the problem. Submit your complete solution (a photo of your written work or typed using LaTeX) as an OpenLab post with title Test #1 Solutions and the type of equation you are solving and with category Test #1 Solutions.

There were different versions of the test with similar questions. Try to choose a problem whose solution a classmate has not already posted.

Step 2

Read your classmates’ solutions and find one for another question on your version of Test #1. Submit a comment on their post describing how you approached that question similarly or differently or any questions or suggestions you have.

    $$ y’ + y = 5*sin*(-4t) $$

    => $$ (dy/dt) + y = 5*sin (-4t) $$

    … (some rearranging)

    => $$ dy + y = 5*sin*(-4t) $$

    (not separable) I psyched myself out on the test and thought it was just a hard separable equation.
