Mathematics Question on Trigonometric Identities
If 2x3−3y2=7, what is dydx equal to (y≠0):
A
(A) x22y
B
(B) x2y
C
(C) x2y
D
(D) None of the above
Answer
(C) x2y
Explanation
Solution
Explanation:
Given,2x3−3y2=7Differentiating w.r.t. x, we get6x2−6ydydx=0⇒x2−ydydx=0⇒dydx=x2yHence, the correct option is (C).
