comment First Plot misses the Show
Try for example g5 = ContourPlot[Cos[x] Sin[y], {x, 0, 2 Pi}, {y, 0, 2 Pi}] /. x : RGBColor[__] :> Sequence[x, Opacity[.5]]

comment Find the tangent at a homogenous point to a curve
@Guesswhoitis. Unless you work mod 16367

comment Find the tangent at a homogenous point to a curve
You need at least a very basic grasp on the syntax before asking a question

comment Plot is discontinuous (it shouldn't be)
Now your gedanken model got the Gedanken Graphics(tm) upgrade. Nice!

comment ParametricNDSolve of differential equation with singularity
NDSolve's integration tricks are Legion. It's very difficult to tell which strategy can solve your problem without taking a look at the expressions.

comment How to control when NDSolve is called inside Manipulate
Not with Manipulate AFAIK, but I may be wrong

comment How to control when NDSolve is called inside Manipulate
You may consider something like Manipulate[ s = solveDiffEq[a0]; Manipulate[s /. t -> t0, {t0, 0, 1}] , {a0, 1, 2}]

Perhaps you may want to use Tooltips instead

Voted to close. I don't think this question is answerable without further info

Labeled[Plot[-x^2 - 4, {x, 0, 5}, ImageSize -> 500, AxesOrigin -> {0, -1}], {"Y axis", "X Axis"}, {Left, Top}] ?

comment Manipulate with a function as a parameter
@user1337 Manipulate[ nd = NDSolve[{(a /. y -> y[x]) == y'[x], y[0] == 1}, y, {x, -5, 5}]; GraphicsRow[{ Plot[y[x] /. nd, {x, -5, 5}], ContourPlot[a == 0, {x, -5, 5}, {y, -5, 5}]}], {{a, -Cos[y] + Sin[x]^2}}]

@user1337 Yep. I think so too. Thanks for the accept

comment Need help with the Lagrange multiplier method
@Guesswhoitis. Didn't work when I tried it first. Tried again after reading your comment and the obvious conclusion is that I made a mistake the first time. :)

Sorry, but I am getting the exact output you want. (Mathematica v9)

@Mr.Wizard Probably means "Integer", "not integer". Language issues

comment Switching ArcTan argument from a sequence to a list
I don't think you need special considerations. Just points = RandomReal[{0, 1}, {10, 2}]; ArcTan @@@ (Differences@points) will do
