The cosine and the versed sine are together equal to the radius, so that the versed sine is always 1, less the cosine.

If, on the contrary, I enlarge the angle A O C by moving the radius O C toward O B, then the sine and the versed sine both increase, and the cosine diminishes; and if, finally, I make O C coincide with O B, then the cosine has disappeared, the sine has become the radius O B, and the versed sine has become the radius

Consider the legacy of hatred and cruelty involved in the doctrines men have built into their creeds where the sine qua non of salvation is absolute acceptance of one particular set of views or else perishing everlastinglyfor only by repudiating history can they disavow it" "You're not quite accurate," I put in.

So always in practical operation that law is absolutely true which we observe to be approximated to more and more nearly as we consider smaller and smaller angles, that the versed sine of the angle is the measure of its deflection from the straight line of motion, or the measure of its fall toward the center, which takes place at every point in the motion of a revolving body.
