Quick Trigonometry Question

[Ordinathorreur]

I looked at the tutorials here on Kirupa, but I'm still having some trouble.

I have the value of the angle, and side A. Could someone help me with the formulas in AS to calculate sides B and C, or throw me a clear link so I can try to figure it out myself. See the pic for details

Thanks a bunch for taking the time to help.....

This post can help.

if you cant figure it out, I'll walk ya through it

degreeAngle = 30; // known angle CA in degrees
radianAngle = degreeAngle*(Math.PI/180); // converts known angle to radians
side_A = 5; // length or value or known side A
side_B = side_A*Math.sin(radianAngle); // calculates length or value of side B
side_C = side_A*Math.cos(radianAngle); // calculates length or value of side C

Check out senocular's thread... its impressive. I told you how to do it but he teaches you what you are actually doing...

I figured out that I don't actually need what I was asking for, in fact it's a lot more complicated. Looks like I will be spending the rest of the day breaking my brain. At least I will learn something. Thanks for your posts, that thread is already being very helpful.

Nooooooo! :worried:

What happened to Sens' thread! Where did it go! I need it!

I put a backup of the thread here:

Allright, I'm on the verge of giving up. I have spent 2 days trying to get this working, but I am not succeeding

I am going to explain my problem.

Take a look at example.swf
The dotted lines are where I need the cam to be.
Click one of the boxes (only once, you will have to reload to see it again, i quickly modded my AS to give you an example)
As you can see in the first movement, it ligns up nicely, the dotted box is in the center of the screen, it's just slightly rotated. Then I rotate my main mc to compensate, but obviously it goes off screen. Not good. This is my problem.

Example2.swf shows the same movement, but done continuously. This is more like I want it to look. (you can click the boxes more often, but wait till the movement is over)

I have also included a .fla which I have commented quite nicely. Please take a look and help me out with my trig problems..... or this experiment is destined for the bin.

Here is the .fla (http://www.danieltodd.com/navigation.fla)
