Title: Curse math! Anyone get sine, cosine, and tangent?
Post by: Doodle on April 28, 2008, 06:19:14 PM
OK I have this triangle. Right angle of course. It looks like this:

      |\
      | \
      |  \    14
x   |   \
      |    \
      -----   48 degrees


I'm thinking I use sin, but not really sure...

What you do is this:
...intercourse  why can't i remembeeeeeeeeeeer

I'm in pre-calc, I should remember this, but my brain is mush right now. Sorry.

you use sine because it's opposite over hypotenuse.  sin(48?) = x/14, solve for x using inverse sine.

The only thing I remember is to help you out, use the name of the Indian:

SOH CAH TOA

I thought it was more like a volcano.

Like Krakatoa.

My teacher made up a story about it being an Indian so I stick with that one.

that's not good, it's fundamental trigonometry.

ARGH...

I don't want to have to ever do that stuff...

This math is next year for me. We actually skipped over trigonometrical functions in our book.

Problem solved. Take calculus to solve all your problems.
