Question

Is (dy/dx)^2 equal to (d^2y)/(dx^2)?

Answer 1

not that I can tell

Answer 2

NO..

Answer 3

one says to square the derivative; the other says to take the derivative of the derivative

Answer 4

Suppose:
dy/dx = x^2+x
(dy/dx)^2 = (x^2+x)^2
d^2y/dx^2 = 2x+1

Answer 5

in some odd case it might be true .... but as a general rule.. no

Answer 6

well yea.. it will be true when:
(y')^2 = y''
solve the diff eqn
