Question
The general solution, (t) satisfies the following second
order differential equation
ay" + by' + cy = 3 cos 2 t
Where a,
b and c are constants and a + 0. The (t)
а
depend on whether
b² > 4ac, b² = 4ac or b2 < 4ac.
i) Construct TWO (2) different general solutions, (t) and
solve the models with initial conditions y(0) = 2 and y
(0) = 0 by using undetermined coefficient method. Plot
both general solutions (t), for interval of 0 <t s 5 and
discuss the differences.
ii) Construct ONE (1) general solution, (t) and solve the
model with initial conditions y(0) = 2 and y'(0) = 0 by
using Laplace Transform.
