ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:

Read them. You will be expected to follow them.

    soh cah toa question

    so I'm looking at this site:
    http://id.mind.net/~zona/mmts/trigon...tTriangle.html

    2/3's way down there is a cool little screen that allows you to change the input angle to get different hyp and adj sides measurements...ok...no problem.

    Question...what makes no sense to me and I haven't had this shit for a while...and I'm sure there is like another formula that determines this...set the angle to 45 degrees.

    Ok no issues...play with the scroll bar...uhm why doesn't the hypotenuse length change? How would that effect the formula? What I'm really wondering is WHY the hyp side is staying at that set length...why did they set that?

    is sin(45) always the same then? What about different length sides with the same angle (45)? I deff. missing something here

    The relationship is between x and y, and the hypotenuse is merely the result of that relationship; thus it can be considered a constant once the relationship has been reduced to the 1st degree.


    sooo....

    you don't need to vary the hypotenuse to understand the trigonometric relationship between x and y. In fact when it is constant it is much easier.


    memorize the circle below, it will make your life a lot easier. notice the radius of the circle never changes, where radius = the hypotenuse you speaker of.



    have fun

            fixed. I don't think those websites liked being hot-linked.
