comment How to Integrate trivial products of DiracDelta
don't we need to make some assumption on f to eval this? Suppose f[x]=1/(DiracDelta[1 - x] DiracDelta[x])

comment Assumptions and Conditions in Integrate Function in Mathmatica
FYI your Assumptions only apply to the outermost Integrate. Try setting $Assumptions (or better make it one triple integral). (cant test here,,) Also if all else fails you can wrap the whole thing in Simplify with your assumptions as an argument.

comment Range errors when plotting solutions of systems of equations
Ahh.. Reduce shows the solution which is just a line. b==-c==+/-Sqrt[1-a^2]

comment Range errors when plotting solutions of systems of equations
I was going to suggest making a scalar expression, (a^2+b^2-1)^2+()^2+()^2 ==0, however there does not appear to be any solution ( or only a single point , or very small region, so contourplot3d doesn't work )

@JacobBond you should work the word "simultaneously" into the question..

comment Range errors when plotting solutions of systems of equations
The docs are not absolutely clear on this but I think ContourPlot3D can only handle a single scalar equality.

comment How do I solve for the roots of $\sin(x) - x^2=0$?
it would be might helpful if the Solve/NSolve warning msg suggested trying the domain Reals..

comment Constantly rotating 3d contour plot (ideally as a .gif)
I'd strongly encourage you to find a much simpler example to work with. This one is horrifically slow.

comment Exporting pdf with a precise page dimension in metric units, rather than printer points
my opinion this is not a duplicate. The issue is I think very specific to pdf and I would suggest editing your title to reflect that.

you should not have the underscores in the last expression
