Graph the curve with parametric equations x = (1 + cos(16t)) cos(t), y = (1 + cos(16t))sin(t...
Are you looking for this?
ParametricPlot3D[{(1 + Cos[16 t]) Cos[t], (1 + Cos[16 t]) Sin[t],
1 + Cos[16 t]}, {t, 0, 2 Pi}]
or perhaps you want something dynamical?

Help me plot this function
To understand what you did wrong observe the differences in the colors between your code and mine. What do you see for the Sqrt function? Something is different.
Something is also different for the va …

How to remove part of the solution in ContourPlot
You can use Exclusions
ContourPlot[l^2*Sin[a]^2 - Sin[l*a]^2 == 0, {a, 0, 2*Pi}, {l, 0, 5},
PlotPoints -> 500, Exclusions -> {l == 1}]
Edit: addressing the comment.
This is not elegan, it's a ve …

How to fill a PolarPlot
Another way was suggested by @kglr and it works in the following manner:
PolarPlot[
0.5 (7.89 + 8.12 Cos[4 t] + 8.526 (Sin[4 t])^2), {t, Pi/4,
3 Pi/4}] /.
xx_Line :> {xx, Dynamic[Lighter@Light …

How to plot a function with changing parameter?
If you want a to be an arbitrary parameter you can try to use Manipulate
Manipulate[
Plot[2*(a^2 - x^2) - ((a^2 + x^2))^2, {x, -10, 10}], {a, -10, 5}]

Creating a Plot of Two Functions with Different Colors
There's a mistake with the brackets. The following works fine
f[x_] = Sin[x]
g[x_] = Cos[x]
Plot[{Sin[x], Cos[x]}, {x, -2*Pi, 2*Pi},
PlotStyle -> {{Black}, {Blue}}]

How to optimize the tangent equation of a curve at a certain point?
Maybe I am missing something, but I don't see what.
Anyway, with a minimal amendment of the code in the OP we have:
f[x_] := Log[1 + x] + x E^-x
g[x_] := D[f[x], x] // FullSimplify
point = {0, f[0]}

How to modify the label of the power functions?

If yes, then you want to have a look at ToRadicals

Root[#^3 - x^2 &, 1], Root[#^8 - x^7 &, 2], x, x …

How to obtain the ImageSize?
This is not the best answer, but perhaps a good starting point.
