Section 2.1 Section Title
A
pulse is a single, non-repeating disturbance that propagates through space and time, transferring energy and momentum.
A
wave is a continuous, periodic succession of pulses.
So the integral \(\int_0^2 3x(x^2+1) \, dx = 18 \)
\begin{equation*}
\frac{d}{dx} \int_1^x \frac{1}{t}\, dt = \frac{1}{x}
\end{equation*}
\begin{equation*}
\int_a^b f(x)\, dx = F(b) - F(a)
\end{equation*}
