{\displaystyle \left({\frac {dx}{dh}}\right)^{2}={\frac {2r}{h}}-1.} The involute of the cycloid has exactly the same shape as the cycloid it originates...

For involute gears, the teeth always exert force along the line of action, which, for involute gears, is a straight line; and thus, for involute gears...
