Description:

This patch speeds up sin() and cos() functions of Basic 2.0 up to 10 times.

This program changes BASIC sin() and cos() to calculate sinus and cosinus 3 to 10 times faster using approximation tables.

If you set the program to calculate in degrees your calculations will be even faster.

Its settings:

sys49152 :activates the fastmath

sys49155 :disactivates the fastmath

sys49158 :sets to find sine in radian

sys49161 :sets to find cosine in radian

sys49164 :sets to find sine in degrees

sys49167 :sets to find cosine in degrees

This program is installed at $c000-$c2af.

I wrote this code in 1993, when I was studying physics at METU. I used it a lot to shorten hours of calculations at 1MHz. There was no Internet then; so it took 22 years to undust and publish it here for archival purposes.
