The "opposite" of a negative number, which I prefer to call the "negative" of a negative number, is always positive. Thus, the correct answer here is C.
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)
Answer:
1/9
Step-by-step explanation:
i may be wrong
you add all of them together
then 1/3 times 1/3
