[Solved] Long text inside from{} cause huge spacing

[Yes]

For example:

Code: Select all

"" <= sum from{[x_{i-1},x_{i}] subset K}  %epsilon %DELTA x_i + sum from{[x_{i-1},x_{i}] =  [u_j,v_j] } 2M %DELTA x_i <= %epsilon (b-a) + 2M sum(v_j - u_j) underbrace{""<%epsilon} <= %epsilon(b-a+2M)

Is there a way to avoid it?
Thanks.

If you're referring to the spacing left and right of Σ, it is there so that the summation criteria you've written can be displayed. Perhaps this?

"" <= sum from{binom{[x_{i-1},x_{i}]}{ "   " subset K} } %epsilon %DELTA x_i +
   sum from{binom{[x_{i-1},x_{i}]}{"="[u_j,v_j]} } 2M %DELTA x_i <= %epsilon (b-a) + 
   2M sum(v_j - u_j) underbrace{""<%epsilon} <= %epsilon(b-a+2M)

If not, how would you propose to display the summations without this spacing, while showing the criteria?
