I am using \documentclass{report}
and \usepackage{amsmath}
. My problem is relation symbols such as \backsim \lesssim \gnsim
are not working. Everytime I try to use such symbols error comes !Undefined control sequence.
Please guide.
[Tex/LaTex] amsmath undefined control sequence

I'll just turn this into an answer.
amsmath
provides very few symbols, so in most cases [1] you need to load bothamsmath
andamssymb
[1] Some font packages provide the exact same set of symbols as
amssymb
, in which case you need to either not loadamssymb
at all, or make sureamssymb
is loaded first, such that the font package and override the symbols with the ones suitable for this particular font. (thekpfonts
package is an example of this).
