Sup Bitches?

It goes like this cot (x) * sin(x) = cos(x)

no numbers involved just switching shit around to make cos(x) = cos(x)

i got

``````                      1          *    sin(x)  =  cos(x)
--------          -------
sin(x)              1
--------
cos(x)
``````

How do i deal with that fraction within a fraction bitch?

Thanks
i was wondering what is some of the stuff you guys would consider better than WOW

Put the denominator of of the fraction in the denominator and put it on the top

i.e 1 / (1/2) = (1*2) / 1
...42...
1/sin/cos is really cos/sin hopefully that'll help
i just did these, u in 12?

the cot can be turned into Cos^2/Sin^2

then you have

cos^2 Sin
--------- X --------
sin^2 Sin

= cos^2sin
------------
sin^2

then you factor the top, cross out the sins and you are done. i think, idk this stuff gave me trouble.
In regards to the actual question you had to answer, if you still need help on it, once you have cos/sin you multiply that by sin giving you sincos/sin which allows you to cancel out the sins giving you cos
cotangent = 1/(sin/cos) which is the exact same thing as (cos/sin)

remember that (2/3)/(3/4) is the same as (2/3) x (4/3), same logic applies here

(cos/sin)x(sin)=cos because the sines cancel out and you are left with the cosine.

Speaking of trig identities, I have a quiz on verifying identities and the like tomorrow in my precalc class which I should be studying for. Thanks for the reminder.

DivinEdit: And don't listen to anybody who tells you to use the Pythagorean identity. That is just over-complicating the problem.

Epic post. Wish I could say more, but I don't know much about the subconscious and other psychological stuff.

cant cancle when mutiplied i dont think, and its not sin/sin= 1 its sin^2 + Cos^2 = 1

you will have to factor when you multiply then cancle

No, you don't. Cot=cos/sin = 1/tan =1/sin/cos.
Cot*sin=Cos/sin * sin/1 = sincos/sin.

The sines divide out, and you're left with cos.
cotx*sinx = (cosx/sinx)*sinx = cosx
Come on, TS, seriously...

Though our skin may not touch skin
Look for me with the sun-bright swallow,
I will come on the breath of the wind
