thanks for your ideas 0xDEADBEEF very nice :)... Chrisharvey a graph digitiser is a program that take as input a graph and as output gives an approximation of x,y coordinates (on 2d space) correct? What kind of input does this kind of program requires? Image files? If yes, are there any other...

hahaha ... Ye sure... I would like something like that as well if it's eatable ...

I would like to hear from you guys, ideas about a program that can be handy, for a scientist or a student, in the field of chemistry, physics or mathematics. I want to create something which does not exist on the market but can be helpful for many. I am a computer scientist currently...

Yes problem solved o:)

ok sorry i just read the post again you are right i am just a little dizzy to much math for me those days... :)

You said that my calculations were wrong in your second post ... In your first post however you just said what i said, you sounded like a parrot.

Ok so my calculations were wrong i will try and work it out then, thanks. And btw i admire that you are helping people with their math problems but you did not help me with your first post, capitoo:)?

Yes you told me exactly what i did :rolleyes: but for some reason i am stuck at this step. Its not that straight forward for me as it is for you

Sorry but i don't know how to use latex yet or to add mathematical symbols somehow. Homework Statement Prove that 1-sin2θ/cos2θ = 1-tanθ/1+tanθ Homework Equations sin2θ = 2tanθ/1+tan2θ and cos2θ =1-tan2θ/1+tan2θ I have allready proved from a previous exercise those two above so...
