The term "trigonometry" was derived from Greek τρίγωνον trigōnon, "triangle" and μέτρον metron, "measure".. The modern words "sine" and "cosine" are derived from the Latin word sinus via mistranslation from Arabic (see Sine and cosine#Etymology).Particularly Fibonacci's sinus rectus arcus proved influential in …

WitrynaAnd so pi over three, would look something like this, this is pi over three radians. And the cosine and sine can be determined by the X and Y coordinates of this point where this radius intersects the actual unit circle. The coordinates here are going to be cosine of pi over three radians and sine of pi over three radians.
