Re: OMO maths ?
You have the adjacent (6mm) and want to work out the opposite so you have to use tan.
Tan23 = x/6 where x is ??mm |

Re: OMO maths ?
God, it's been a while since I've done these!
tan 23 = o / 6mm. 0.424474816 = o / 6mm o = 0.424474816 * 6 o = 2.546848897 So 2.5mm, which looks about right against the diagram. |

Re: OMO maths ?
Very useful and straightforward formula, and if you remember SOH-CAH-TOA sound like 'soccer tower' you won't forget it. Last edited by thulfi; 02-04-13 at 11:54 PM. |
