Derivative AnimatorMATHS P1 · CALCULUS · 35+ MARKS

The tangent line is the derivative. Watch it slide along the curve. See how the gradient changes at every point.

x = 0.00
f(x)2.00
f'(x) — gradient of tangent0.00
Tangent equationy = 2.00
Key insight: When f'(x) > 0, the curve is going up. When f'(x) < 0, going down. When f'(x) = 0, it's a stationary point (max, min, or inflection). Watch the value of f'(x) flip sign as you slide past a turning point.
