View Full Version : Computation Question

Are there any computer programs, or computer systems out there that can compute trigonometric values for cosine for large numbers like

cos((pi)*t) = cos((pi)*2.34579^2000) to an accuracy of three decimal spaces? Where pi is the number 3.1415.....n

If so, what systems are available, how might I get one, or rather, how much do they cost?

Also, If such a system exists, how long would it take to calculate something like cos((pi)*2.34579^2000) to an accuracy of three decimal places (to the thousandth's place)?

Inquisitively,

Edwin

Derive 6 will do it. (0.5047333291)

I wonder how Derive goes about that...

It probably just uses a series form with its large number algorithms.
