Please explain, I'd really appreciate it!

**Reiny**, Tuesday, January 14, 2014 at 11:26pmif y'' = sinx

then y' = -cosx + c

given : 2= -cos0 + c

2 = -1 + c

c = 3

y' = -cosx + 3

y = -sinx + 3x + k

given: 0 = =sin0 + 0 + k

0 = 0 + 0 + k --> k = 0

y = -sinx + 3x

you had that, you are done!

you have it expressed in terms of x
