1. The problem statement, all variables and given/known data pt) If A= 4e^4t x sin(4t) 4e^2t x cos(4t) -3e^4t x cos(4t) 3e^2t x sin(4t) Then A inverse is? x= times ^=power sorry for bad format 2. Relevant equations Since it's 2x2 I know you can use the determinant equation 1/(ad-bc) ..etc 3. The attempt at a solution Because of the weird variables I'm not sure how to simplify the multiplication when doing the determination equation.
