Formule
The derivative f′(x) measures the instantaneous rate of change of f(x). It is defined as the limit: f′(x) = lim[h→0] (f(x+h) − f(x)) / h.
Questions fréquemment posées
What is a derivative?
A derivative measures the rate of change of a function. Geometrically, f′(x) gives the slope of the tangent line to f(x) at point x.
What are the basic differentiation rules?
The key rules are: Sum Rule (f±g)′ = f′±g′, Product Rule (fg)′ = f′g + fg′, Quotient Rule (f/g)′ = (f′g − fg′)/g², and Chain Rule (f(g(x)))′ = f′(g(x))·g′(x).
What is the derivative of eˣ?
The derivative of eˣ is eˣ itself. This unique property makes e (Euler's number ≈ 2.71828) fundamental in calculus.
How do I find the derivative of a composite function?
Use the chain rule: if y = f(g(x)), then dy/dx = f′(g(x)) · g′(x). For example, d/dx[sin(x²)] = cos(x²) · 2x.
