The definite integral of a function $f(x)$ from $a$ to $b$ is denoted by $\int_a^b f(x) dx$.
\subsectionParametric Equations
A parametric equation is a set of equations that express $x$ and $y$ in terms of a parameter $t$. The definite integral of a function $f(x)$ from
\subsectionIncreasing and Decreasing Functions
The derivative of a function $f(x)$ is denoted by $f'(x)$ and represents the rate of change of the function with respect to $x$. The definite integral of a function $f(x)$ from
