A trigonometry question
« on: August 15, 2007, 07:03:29 PM »
I have done some reading on trigonometry (at least I think that's what I need) but I still can't work this out!



Assuming you know the lengths of sides x and y, how would you calcualate angle a?

TIA

Thanks! Do you know which C trigonometry function will convert the result of y/x to an angle?

Never mind, I have just found out that the language I'm using has a direction() command which calculates the angle in degrees between two points, which is exactly what I'm trying to do. Thanks anyway Cass.
