Question 43

Multiple Choice

Solve dydt=y2+1\frac { d y } { d t } = y ^ { 2 } + 1 if y = 1 when t = 0.


A) y=arctan(t+π4) y = \arctan \left( t + \frac { \pi } { 4 } \right)
B) y=arctan(tπ4) y = \arctan \left( t - \frac { \pi } { 4 } \right)
C) y=tan(t+π4) y = \tan \left( t + \frac { \pi } { 4 } \right)
D) y=tan(tπ4) y = \tan \left( t - \frac { \pi } { 4 } \right)
