I am studying calculus and I need to compute the arc length of a curve defined parametrically. For a curve given by $(x(t), y(t))$ for $a \leq t \leq b$, the arc length formula is:

I'm studying linear algebra and I need to solve systems of equations using Gaussian elimination. For example: \begin{align*} x + 2y + 3z &= 9 \\ 2x - y + z &= 8 \\ 3x - z &= 3 \end{align*}

I'm studying A-Level calculus and I can state the Mean Value Theorem: If $f$ is continuous on $[a,b]$ and differentiable on $(a,b)$, then there exists $c \in (a,b)$ such that:
