Find the solution to the differential equation dydty22t if y
Find the solution to the differential equation dy/dt=y^2(2+t), if y=7 when t=1
y=?
y=?
Solution
integral dy/y2 = integral (2+t)dt
- 1/y = 2t + t2/2 +C, C= integration constant
at y = 7, t = 1
-1/7 = 2.1 + 12/2 + C
C = -37/14
- 1/y = 2t + t2/2 - 37/14
or y = - 1 / (2t + t2/2 - 37/14)
