for mathematical interrested people an interresting question:

how to calculate a sine function without the sine function

[i mean without a calculator or the function sin()] ?

huh, depends …

if you need the sin() function for a program, you can use a pre-calculated table. if you need to calc it all on your own … damnit, I knew this in my c64 days

hey, this is not that impossible:

some very well known triangle theorems could really help you…

hey !

thats not that easy

yes you can do it graphically, but then CALCULATING it without sin(x)

is really hard !!!

i had a nice bookmark explaining how to calculate sinus using taylor series, but the page went offline. here, a huge thank to google for its caching abilities

This is a link that should help if you need to go further to the past. I’ve found lots of pages that I thought were gone forever.

What these guys are trying to do is basically save snapshots of websites at certain points of time. Grrreat.

yeah… archive.org is pretty cool. actually i know this page for a long time, but when it comes to availability google is way better.

HAHAHAHA!

we were learning this in school last week!

sine and the unit cirlce!
