Hi(adsbygoogle = window.adsbygoogle || []).push({});

(I hope this is the right place to post this - sorry if it's not)

Say I have a line (in the graphic is shown a 10mm but it could be any length) and it rotates around a point at one end.

What is the formula to get the length along the x axis directly under the other end of the line. In the graphic that would be the distance between points a and x.

Thanks

EDIT - I have tried using a Taylor Series but it's been a long time since I was a school :-)

It's simple on a calculator with the cosine of the angle and the line as a hypotenous but I am trying to get the maths formula.

Have something to add?
