1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

u hav a ruler? @safe plume can help with graphing

\begin{tikzpicture}
\begin{axis}[
axis lines=center,
xlabel={$x$},
ylabel={$y$},
xmin=-.001,
xmax=.001,
title={Limit behavior of $\sin(x)/x$},
legend style={at={(0,-0.15)},anchor=north west,fill=none}
]
\begin{scope}[thick, samples=201, smooth]
\addplot[domain=-.001:.001, yellow] (x,{sin((x)r)/x});
\addlegendentry{$y = \sin(x)/x$};
\end{scope}
\end{axis}
\end{tikzpicture}

you can replace the sin((x)r)/x with the function that u wanna plot, and specify the xmin, xmax, ymin and ymax;

im sorry im a little confused on what you just did

i mainly wanted help with part (b), sorry i should have specified that

[woeful moat]

,calc derivative('2x^2 + 3x -4', 'x')

[safe plume]

Result:

4 * x + 3

@safe plume can also help with that
