We first need dy/dx.
dy/dx = -2sin(x/2)(1/2)
dy/dx = -sin(x/2)
We now find d^2y/dx^2.
d^2y/dx^2 = -cos(x/2)(1/2)
d^2y/dx^2 = -(1/2)cos(x/2)
U + v = {-3 + -3, -5 + 1} = <span> {-6 , -4}
</span>u + v = <span> {-6 , -4} </span>
Multiplying out the expression, you get
2x^2 -(1/3)x . . . . . . matches selection D
