Part I First order ODES For each of the first-order ODEs, solve the solution using ode45, then plot the solution on the given interval: 1. y'= -2ty, y(0) = 10, 0≤ t ≤ 5. 2. y' y sint, y(1) = 4, 1 ≤ t ≤ 10. 3. y' =√√¹², y(1) = 0.5, 1 ≤ t ≤ 20. 4. (1-t²) y'= 2y, y(2) = 2, 2 ≤ t ≤ 30. 5. y'= 2te-3t 3y, y(0) = 5, 0≤ t ≤ 8.
