coincidence with pi/2?Hey, I looked on a graphing calculator and found that the limit of acos(x)(pi/2) as x goes to 0 equals 0. Here's the only iffy part: is pi/2 a coincidence just popping up as some random number, or does the acos function acually really relate to pi/2? Linux FTW #2 20061208 13:58:00
Re: coincidence with pi/2?its because acos is the inverse function of the cosine function. The reason pi appears is because we're working with radians. A logarithm is just a misspelled algorithm.
