Question
You can verify that the differential equation: 2t°y" - 4t(t + 1)y + 4(t +1)y= 0, t> 0
has solutions y1 = 2t and y2 = 3t exp (2t).
a. Compute the Wronskian W between y1 and y2.
W (t) =
| 12-e2t
b. The solutions y1 and y2 form a fundamental set of solutions because there is a point to where W(to) + 0:
W
# 0.
Note: It simply wants you to find some number to to put into the first answer blank and plug into the Wronskian to get something nonzero, which goes into the second answer blank.
