Trigonometry

Post by killer »

Hi guys, I really need some help with trigonometry... especially with this one.

Establish an identity

A= Data
B= Data

1+ cosA + sinB/1+cosA-sinB= secA + tan A

Here's a helpful site with trigonometry identities.

http://www.clarku.edu/~djoyce/trig/identities.html

I'd appreciate it... Thanks

Edit: If there is any easier way to memorize the identities please let me know :)

I suck at trig, plain and simple. I was horrible with alegebra also...which is really odd because I was a wiz at calculus. I was pretty damn good with statistics.

But I digress, I suck at trig.


Good luck my man. I need to dust off my scientific calculator.

There's a site out there that will do Math problems(including trig), step by step to show you how to do it.

I seriously hated trig functions and I'm 100% sure that I willl never use it again in my life.

Trig was pretty cool, but that was like 7 years so I can't say I remember anything but SOHCAHTOA.

You will use it if you want to do acoustic engineering:

Here is a song that may help:

Haha, Thank you ru! I remember the story of soh cah toa. Once my high school teacher told us about it, and I should've taken TRIG in high school, but for some BEEP reason I dropped it :(

S-sine
O-opposite
H-hypotenuses

C-cosine
A- adjacent
H- hypotenuses

T- tangent
O- opposite
A- adjacent

PS: It's not that I completely suck at TRIG, it just this problem giving me headache. I tried working with right hand side to get the left hand side and got stuck.. now I'm trying to work with left hand side to get the right hand side... I'm almost there!!

Thank you all :)

Killer GTFO. Do your own homework. :lol:

Just kidding, but I'm sure you solved it by now. However, if you did not, pm me the stuff.

On another note, Trig was fun. It's even more fun when you use it in physics. It's odd how I like the field of mathamatics yet I went into the field of biology.

And WTF Vapor. It's wierd that he has not commented in this thread; either to criticize you, or solv...nah, just criticize you.

Hey that was harsh. I did get accepted to Berkeley. I just wanted to go to UCLA more.

Anyways I went where the money was and in the end a place that I knew I was going to dominate. :D
