I am currently studying GCSE Maths. I believe there is a way to find the $\tan$ of $\theta$ using the line $x = 1$ and a circle radius of one on a graph. Is there a diagram I could use to explain this?
Method for finding $\tan(\theta)$ using $y$

0Where you wrote $\tan(x)$ in your title, did you mean $\tan\theta$, so that $x$ and $\theta$ are two different names you're using for the same thing? – 2017-02-15

0Yes, sorry. I originally was going to ask another question. – 2017-02-15

1The line is $x=1$. https://en.wikipedia.org/wiki/Trigonometric_functions#/media/File:Unitcircledefs.svg – 2017-02-15

0With $x=1$ it would much more easier :) – 2017-02-15

0Yes, you are correct. I have now made the necessary edits. – 2017-02-15

0What's "GCSE"? $\tan(\theta)$, where's the $\theta$? Are you referring to the slope of the line $x=1$? – 2017-02-15

0@stud_iisc GCSE stands "General Certificate of Secondary Education", something that is referred as "Board Exams in India". See the comment by Yves on what he is referring. $\theta$ does not matter here. – 2017-02-15

0@A---B Thanks for pointing out. But what does the OP require now? – 2017-02-15
