Wrong values with COSINE!

[BigWumpus]

It's not at all as you thought dear Mr intelligent...

By the way, thanks for your friendly reply! you're so much sociable and i think all your friends envie you

there real problem is that i have tried your small equation... maybe befor you were born! but it didn't work at all..... i wonder what is the mistery and this is why i have asked a help....

THIS EQUATION DOES NOT WORK... just try it and you will see! don't just "talk", try and tell me the result... are you getting real values???

You don't know to whom you are talking - Stupid!

I worked with computers long time before there was a PC. We worked with this cases with blinking lights and switches in front...
I think, I know what bits look like and how to implement calculations ....

And now - I'm sitting around, waiting for you and all your friends...
But THEY will not help you!

Some of you are good ones and others are.... really bad! especially the one of lights and bulbs! haha.

Dear Sirs,

my question was simple and clear. You do not have to worry about what i am doing and why i did not use a table! you really have smart ideas there! but i just needed to see if there is one single HEAD of you able to solve this matter...

i have 3 possibilities other than using TABLES.. but i still only have to solve this matter which is:
i need to use the provided "cosine" question in the PicBasic Pro tutorial in order to get the usual answers... like cos 0 = 1 and cos 90 = 0 etc etc

so just in case someone has a method, please say it and give the method otherwise, if it is only for dummie answers and stupidities, i have enough of IMPORTANT things to deal with and not obliged deal with bulbs and lights or anything else....

By the way Mr Bulb, as long as I DUNNO WITH WHOM I AM TALKING.... why don't you show me what do you have INSIDE your brain? and not just what you USED to do in the past?

maybe still dealing with bulbs till now?..........

Come on people! the world has changed! lol

thanks for:

but in my application, i am not using x or y...

i am just getting a phase shift from a Phase Locked-Loop, transforming this number to degree and then, i need the cosine of this number...

All the problem is that "cosine" was made to give an answer in two's complement... and this is bad...... i need the normal answers...

Hi,

From the link:
http://www.emesystems.com/BS2math3.htm#arcCos

Here is a simple demo program that illustrates the use of the SIN and COS on the BASIC Stamp. It steps through all the angles from 0 to 360. The angle is printed in degrees and the cosine and sine of the angle are printed as decimal numbers in the range of -1.00 to +1.00.

Thanks agains Luciano,

but i really do not need them in this way... i don't mean to be rude or not caring but i really really do not need them like this..
