This article provides a step-by-step guide to calculating derivatives, starting from the formal definition and progressing through essential rules, special techniques (implicit and logarithmic differentiation), and higher-order derivatives. For a function ( y = f(x) ), the derivative, denoted ( f'(x) ) or ( \fracdydx ), is defined as the limit of the difference quotient as the interval approaches zero:
