Question 99

Multiple Choice

Find the solution of the initial-value problem dydt=y+t2yt2\frac { d y } { d t } = \frac { y + t ^ { 2 } y } { t ^ { 2 } } , y(1) =2y ( 1 ) = 2 .


A) y=2et+(1/t) y = 2 e ^ { t + ( 1 / t ) }
B) y=3et−(1/t) y = 3 e ^ { t - ( 1 / t ) }
C) y=2ety = 2 e ^ { t }
D) y=2e1+(1/t2) y = 2 e ^ { 1 + \left( 1 / t ^ { 2 } \right) }
E) y=2e1/ty = 2 e ^ { 1 / t }
F) y=cet−(1/t) y = c e ^ { t - ( 1 / t ) }
G) y=cet+(1/t) y = c e ^ { t + ( 1 / t ) }
H) y=2et−(1/t) y = 2 e ^ { t - ( 1 / t ) }
