A. A ball at 1200K is allowed to cool down in air an ambient temperature of 300K. Assuming heat is lost only due to radiation, the differential equation for the temperature of the ball is given by de -2.2067 x 10 12 (e* - 81 x 10"), e(0) = 1200K dt Where 0 is in K and r in seconds. Find the temperature at t=480 seconds using Euler's method. Assume a step size of h=240 seconds.

Q3.
A. A ball at 1200K is allowed to cool down in air an ambient temperature of 300K.
Assuming heat is lost only due to radiation, the differential equation for the temperature
of the ball is given by
de
-2.2067 x 10 12 (0+ - 81 x 10°), e(0) = 1200K
dt
Where 0 is in K and t in seconds. Find the temperature at =480 seconds using Euler's
method. Assume a step size of h=240 seconds.
B. Find the sum (one) of the following series:
1- Eo 2
2. E1(-1)"
