Nested cases, alignment and numbering
Clash Royale CLAN TAG#URR8PPP
6
I have tried all different sorts of solutions including align, aligned, cases and equation to have the result I get with this code except that I want numbering for the three lines in the aligned subenvironment. Do you have a solution or better way of representing this?
beginequation
left{
beginaligned
partial_t u(vecx,t) - alpha Delta u(vecx,t) &= f(vecx), &&(vecx,t) in Omega times J, \
%
u(vecx,t) &= 0, &&(vecx,t) in partial Omega times J, \
%
u(vecx,0) &=
begincases
rho, &vecx in T \
0, &vecx in B textbackslash T
endcases
&&vecx in B
endaligned
right.

Don't usetextbackslash. Usesetminusinstead.

@Mico, ups, i didn't check used symbols :-(. corrected now. thank you very much!

@Mico, do you have an short explanation of why to use setminus instead of textbackslash?
– Robin Hellmers
Dec 10 at 19:51
@RobinHellmers -textbackslashis a text-mode command. In contrast,setminusis a math-mode command. In your screenshot, note that the spacing around the backslash character is too tight, when compared to the screenshots posted by Zarko and myself.
