Editing Orbital inclination change (section)

== Circular orbit inclination change ==

Where both orbits are circular (i.e. <math>e = 0</math>) and have the same radius the [[Delta-v]] (<math>\Delta v_i</math>) required for an inclination change (<math>\Delta i</math>) can be calculated using:
<math display="block">\Delta v_i = {2v\, \sin \left(\frac{\Delta{i}}{2} \right)}</math>
where <math>v</math> is the [[Orbital speed|orbital velocity]] and has the same units as <math>\Delta v_i</math>.<ref name=Braeunig/>
