Step 1.append("text") . Differentiate both sides of the equation. The derivative of with respect to is . x = x + dx; y = y + dy; You should not update the position as written above in real life. Step 3.
I see, so "dx" is simply shorthand for the denominator of the limit where dx→0 when dx = h and h→0. The dy is dependent on the dx. In fact, Leibniz himself first conceptualized d y d x \frac{dy}{dx} d x d y as the quotient of an infinitely small change in y by an infinitely small change in x x x, called infinitesimals.
