Algebra is very easy. I'm not too sure what Algebra is....

[Zero7]

Sorry, what? your last statement made absolutely no sense.

[Malevolent]

Yeah, I agree with Zero on that last statement.

And yeah, you do memorize a lot of stuff in trig. And I think memorizing things is retarded (but that is why you should try to find out where stuff comes from; then you don't have to memorize). Memorizing leads to boring.

IR: SOHCAHTOA is basically the most basic thing you memorize in trig.

[duherman]

So you're saying theres more?

[Dark]

oh heck ya there is more but i don't know when you will hit the extra stuff

Intensity rising, SOH CAH and TOA only works on triangles that has an angle on 90degrees. There are also Sine and Cosine thingies which applies to every triangle.

Sine:
Sin(A)/a = Sin(B)/b = Sin©/c
This can be used to calculate other sidelenghts or other angles if you know a pair(ex. A and a) and then one part of another pair(ex. just C, but not c).

Cosine:
c^2 = a^2 + b^2 - 2abcos©
can be used to calculate a side opposite of an angle, where you know the two adjacant sides. and also to calculate an angle if you know all 3 sides.

- basically you can calculate every parts of the triangle if you know 3 other parts, with the exception of you only knowing the angles.

I wrote Soh Cah Toa on my calculator, I wonder if that's considered cheating on the test.

i'd count that as notes, depending on if that is allowed or not it would be cheating.

@swift.... no, no i didn't. SOH CAH and TOA is just a sentence, which you can try and remember. What i said is based on if you know what Tan, Sine and Cosine spits out, which is based on the definition of them.
