Verify that the indicated function is an explicit solution of the given differential equation. Assume an appropriate interval I of definition for each solution. 1. 2y #x27; + y = 0; y = e^(-x/2) 2. dy/dt + 20y = 24; y = (6/5) - (6/5)e^(-20t) 3. y #x27; #x27; - 6y #x27; + 13y = 0; y = e^(3x)cos(2x) 4. y #x27; #x27; + y = tan(x); y = -(cos(x))ln(sec(x) + tan(x))
