OT: Trigonometry Help

[Goldeneagle]

I use trig almost daily to program my machine here at work. I consider the way I do it the "PRACTICAL" way. Nothing like is taught in college. Seems they like to make it more complicated than it has to be.




Oh, my answer is "D"- All the above.

You will use a little trig in Cal 1, but you will have to know College Algebra like the back of your hand. Most people don't make it through Cal 1 due to the algebra, rather than the actual Calculus.

You have to rationalize the denominator. Multiply top and bottom by (SQR(30)). You will get (17(SQR(30)) over 60 for csc. And for cot you will get 13(SQR(30)) over 60 if I remeber right.

You're correct! Thanks sir.

I'm frustrated because I can't figure this out and I know it's simple, but please help! Haha!

In finding the Cosecant and Cotangent of an angle, this is what I have:

Csc= 17
____
2 sq root 30

Cot= 13
____
2 sq root 30

I know that they cant be left that way, but do I multiply both the top and the bottom by 2 sq root 30 or just sq root 30? Any help from a math guru? Some of my trig class is easy and some hard. Would help to have a professor that wanted to make sure we understand. He just goes too fast. Thanks and no laughing!!!

BTW....Hyp= 17, Adj= 13 and Opp = 2 sq root 30

I'm frustrated just reading the question. But I would let him go one more year.
