Given f ' ' ( x ) = − 36 sin ( 6 x ) and f ' ( 0 ) = − 5 and f ( 0 ) = − 6 . Find f ( π/ 6 )
So I found f'(x) from f''(x) to be 6cos(6x)+csince f'(0=-5 I got 6cos(6*0)+c=-5 where c=-11so for f'(x)=6cos(6x)-11x+cf(x)=sin(6x)-11x+csince f(0)=-6f(x)=sin(6*0)-11*0+c=-6c=-6so f(pi/6)=... more

How do you create a system of equations that has (-2, 5) as it’s only solution?
Your system must have this form: Ax + By = C and Dx + Ey = F. None of A, B, D, or E is equal to 0 or 1. It’s okay if C or F end up being equal to 0 or 1.
