Left align block of equations

Question

I want to left align a block of equations  The equations in the block itself are aligned  but that s not related at all to my question  I want to left align the equations rather than have them centered all the time  because it looks dumb with narrow centered equations   Example  I want to left align this   begin align         vec a   amp    sqrt 3  2  1  2      sqrt 10           vec b   amp    sqrt 1  2  23  2      sqrt 530           cos v  amp    frac 26   sqrt 10   cdot  sqrt 530          v  amp    cos  -1   left  frac 26   sqrt 10   cdot  sqrt 530   right         v  amp    uuline 69 08    degree   end align         but also this   begin align       f x    -1 25x  2    1 5x  end align     How is this done  If it s even possible

You can use  begin flalign   like the example bellow    begin flalign       amp f x    -1 25x  2    1 5x amp   end flalign

Try this    begin flalign        amp   vec a     sqrt 3  2  1  2      sqrt 10   amp          amp   vec b     sqrt 1  2  23  2      sqrt 530   amp          amp  cos v    frac 26   sqrt 10   cdot  sqrt 530    amp         amp v    cos  -1   left  frac 26   sqrt 10   cdot  sqrt 530   right   amp     end flalign     The  amp  sign separates two columns  so an  amp  at the beginning of a line means that the line starts with a blank column

Try to use the fleqn document class option    documentclass fleqn  article     See also http   en wikibooks org wiki LaTeX Basics for a list of other options

User · Answer

The fleqn option in the document class will apply left aligning setting in all equations of the document  You can instead use  begin flalign   This will align only the desired equations
