Solve the following first-order, initial value problem for 0 : ) ( = + y dt dy t y β with 3 ) 0 ( = y for three cases: (a) the parameter 0 = (b) the parameter is positive, say 4 = (c) the parameter is negative, say 4 = Sketch the solutions obtained in (a)-(c) on one graph. Question 2. Consider the following second-order ODE 0 2 2 = + y dt y d . (a) Find ) ( t y if 0 = and ICs are 5 ) 0 ( = y , 1 ) 0 ( = dt dy (b) Find ) ( t y if 4 = and ICs are 4 ) 0 ( = y , 2 ) 0 ( = dt dy . Express the solution in two forms, the complex exponential form and the sine/cosine form. (c) Find ) ( t y if 4 = and ICs are 3 ) 0 ( = y , 0 ) 0 ( = dt dy . Express the solution in two forms, the complex exponential form and the sinh/cosh form.
