Question

Is it possible for this:
¶(dy/dx) = f'(x).......¶ is integrate symbol
¶ dy = ¶ f'(x) dx

My friend said she copied this from teacher's note, i don understand this, is this really possible or there is sum mistake?

Answer 1

\[\frac{dy}{dx} = f'(x)\]\[dy=f'(x) dx\]\[\int dy=\int f'(x) dx\]\[y=f(x)+c\]
