Differentiation Rules
- Power Rule: If ( f(x) = x^n ), then the derivative is ( f'(x) = n \cdot x^{n-1} ).
- Sum Rule: For functions ( f(x) = g(x) + h(x) ), the derivative is ( f'(x) = g'(x) + h'(x) ).
- Difference Rule: For functions ( f(x) = g(x) - h(x) ), the derivative is ( f'(x) = g'(x) - h'(x) ).
- Product Rule: If ( f(x) = g(x) \cdot h(x) ), then ( f'(x) = g'(x) \cdot h(x) + g(x) \cdot h'(x) ).
- Quotient Rule: For ( f(x) = \frac{g(x)}{h(x)} ), the derivative is ( f'(x) = \frac{g'(x) \cdot h(x) - g(x) \cdot h'(x)}{(h(x))^2} ).
- Chain Rule: For ( y = f(u) ) and ( u = g(x) ), the derivative is ( \frac{dy}{dx} = f'(g(x)) \cdot g'(x) ).
Trigonometric Functions
- Derivative of ( \sin x ) is ( \cos x ).
