Answer:

Step-by-step explanation:
remember that,

given that,
thus substitute:

divide both sides by 4/3π:

cubic root both sides:

and we are done!
Answer:
B. Division
You cannot add anything when you divide, so it would remain a polynomial.
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2
