Calculus (IB)
The derivative of a function represents the rate of change of that function at a given point.
It measures how the function's output changes concerning its input.
Power Rule: If f(x) = x^n, then f(x) = x^{n-1}
Product Rule: If f(x) = g(x)*h(x), then f’(x) = g’(x)*h’(x) + g(x)*h(x)
Quotient Rule: If \frac{g(x)}{h(x)} , then f’(x) = \frac{g’(x)*h(x) - g(x)*h’(x)}{[h(x)]²}
Chain Rule: If f(x)=g(h(x)), then f'(x)=g'(h(x))*h'(x)
Derivatives of basic functions like polynomials, trigonometric functions, exponential functions, and logarithmic functions.
Finding Maxima/Minima: Use derivatives to find critical points and determine whether they correspond to maxima, minima, or points of inflection.
Optimization: Use derivatives to optimize functions, such as maximizing profit or minimizing cost.
Related Rates: Use derivatives to solve problems involving rates of change in related variables.
