Converting TAN to angle in order to get SIN and COS is not the best way to do it because you need more calculation and will get higher error.
This is better
SIN=SQRT(1/(1+1/M^2))
COS=SQRT(1/(1+M^2))
Just got an email from the forum, sorry for not replying sooner. Thanks very much for your input. The way that you suggest is indeed better, thanks.

Sick of Eagle ? I can see why
but I am still using it - I don't know about anything better that is also affordable (I like very much Orcad Capture for schematic capture - so easy to work with). Did you try Kicad ? it is also open-source and unlike gEDA there is a version for Windows.

I cant agree more. though Eagle has actually put me off electronics at the moment.
I seem to be a very single minded induvidual. I can only seem to be interested in one thing at any one time. Then ill start doing something else, and that something else is a replacement for eagle. Ill probably get sidetracked in about a month or two though!
I think ive tried just about all of the bad bunch of packages.
I have heard good things about orcad (my uni uses it, for example) but its not for me. I cant even remember all the reasons why i didnt like it, but i think one of the reasons was that it consists of about 10 seperate programs, and another was the slightly dated feel of the UI.
I think that this separate program idea is shite, and is probably a throw back to days gone by.
Here are my biggest problems with eagle:
Visual artefacts pollute the screen a lot of the time, requiring user to zoom in/out to remove them. It would appear that the makers of Eagle, never fully understood Win32API Invalidate method!
The stupid wrench tool. Why group so many options under one roof?
The component search dialog, which is horrendous.
Not enough autonomy. My program will make naming nets, etc easier, and will (hopefully) bring many new innovations to the humble schem capture and pcb editor package market.
Ive decided not to join an open source project myself, as I have a very clear idea of what I want from my program, not to mention that the encapsulated components that Im creating will come in handy as the building blocks for many future projects.
So far, i have completed a large chunk of the vector graphics class that is at the heart of the pcb and schem capture.
Now Im finally free to start on the meat of the application. the electronic specific parts.
Depending on the quality, and stability of the application (which is quite good so far!) and also If i receive enough interest, I may sell the program at a very reasonable price (something aimed at the hobbyist).
My original thoughts were to create a freeware package, but that’s gone out the window, now that I’ve realised how much work (not to mention time) is needed to complete the project to a professional standard.
When my project is nearing a more completed state, I will purchase some web space, and distribute a beta test
