How can I decrease the spacing between equations?
(2) When you have consecutive equations, don’t use separate equation environments but instead use the gather environment provided by the amsmath package. (If the equations should be aligned along, say, their equal signs, use the align environment instead of the gather environment, using the ampersand, &, character as the alignment point.)
How to calculate the spacing between diffraction bands?
If the sine of the diffraction angle is calculated from the distance between diffraction bands on the detector screen and between the screen and the line grating, the spacing (d) between individual rulings on the grating can be determined using the grating equation in the form: ml = d • sin (q)
How to split an equation into three lines?
However, the third equation’s split does not look too nice. In addition, the right-hand side of each equation is very close to the “=” sign. Here is my output:
Why does the size of the diffraction angle decrease as the spacing increases?
According to the equation, the size of the diffraction angle decreases as the line grating space intervals increase. Likewise, longer wavelengths give rise to larger diffraction angles at constant line grating spacings.
Can you have more than one column of equations?
First of all, you probably don’t want the align environment if you have only one column of equations. In fact, your example is probably best with the cases environment. But to answer your question directly, used the aligned environment within equation – this way the outside environment gives the number:
How to number several equations with only one number?
How can I number several equations in a align environment using only one number? The numbering will appear next to the second equation. But it would be better if it appears between the lines of the two equations. In this case how to label this group of equations for later referring to?
