Use laplace transform in solving the ff.:
After cooking for 45 minutes, when a cake is removed from an oven its temperature is measured at 300°F. 3 minutes later its temperature is 200°F. The oven is not preheated, so at t=0, when the cake mixture is placed into the oven, the temperature inside the oven is also 70°F. The temperature of the oven increases linearly until t=4 minutes, when the desired temperature of 300°F is attained; thereafter the oven temperature is constant 300°F for t is greater than pr equal to 4 minutes.
a.) devised a mathematical model for the temperature of a cake while it is inside the oven and after it is taken out of the oven.
b.) how long will it take the cake to cool off to a room temperature of 70°F

Solving Differential Equations using Laplace Transform
Solving Differential Equations using Laplace Transform
a) y" - y' -2y = 0
y(0) = 1, y'(0) = 0
answer: y = 1/3e^2t + 2/3e^-t
b) y" + y = sin2t
y(0) = 2, y'(0) = 1
answer: y(t) = 2cost + 5/3 sint - 1/3sin2t
c) y^4 - y = 0
y(0) = 0, y'(0) = 1, y"(0) = 0, y'''(0) = 0
answer y(t) = (sinht + sint)/2

Use the Laplace transform to find the solution of the IVP:
a.) 2y' + y = 1, y(0) = 2 (answer should be y(t) = 1 + e-t
/ 2 )
f.) 4y" + y = 0, y(0) = -1, y'(0) = -1 (answer should be y(t) =
-sin(t) - cos(t))
Please show work!
