sin2x/cos^2x

OpenStudy (abb0t):

Ok?

OpenStudy (anonymous):

notedd

OpenStudy (bohotness):

i will help you love :D

OpenStudy (bohotness):

:D But is this a real question i feel stupid if its not

OpenStudy (anonymous):

yeah it is

OpenStudy (anonymous):

thank you by the way!

OpenStudy (anonymous):

OpenStudy (bohotness):

your welcome :D

OpenStudy (bohotness):

first of all what do you think is that answer love>?

OpenStudy (bohotness):

:D

OpenStudy (anonymous):

i think it is a typo, because the answer is none of these

OpenStudy (bohotness):

wertid i just put it in and none are here

OpenStudy (bohotness):

-_-

OpenStudy (bohotness):

sin2x/cos 2x = 1 tan2x = 1 2x = 45 x = 22.5 <--- you should have this as a answer

OpenStudy (freckles):

use double angle identity sin(2x)=2sin(x)cos(x)

OpenStudy (freckles):

There should be a common factor on top and bottom

OpenStudy (freckles):

@wolverine75 can you tell me a factor you can "cancel"

OpenStudy (lizz123):

tan2x = 1 2x = 45 x = 22.5 @wolverine75

OpenStudy (bohotness):

I JUST SAID THAT

OpenStudy (anonymous):

well sin2x is the same as 2sinxcosx

OpenStudy (anonymous):

2sinxcosx/cos^2x

OpenStudy (anonymous):

2sinx/cosx

OpenStudy (anonymous):

@freckles

OpenStudy (anonymous):

I'm not sure what to do after this.

OpenStudy (bohotness):

yes it is love

OpenStudy (anonymous):

What do i do after that?

OpenStudy (bohotness):

i is that i send you y nswer?

OpenStudy (anonymous):

?

OpenStudy (anonymous):

@freckles

OpenStudy (freckles):

sin(x)/cos(x) = tan(x) doesn't it?

OpenStudy (freckles):

so what is 2 * sin(x)/cos(x) equal to?

OpenStudy (anonymous):

2tanx ?

OpenStudy (freckles):

awesomeness

OpenStudy (anonymous):

THANK YOU SO MUCH!!!!
