Verify Trigonometric Identity: 2/cosx = 2secx | Doubtful Answer?

[Mozart]

Hello, I just worked out a trigonometric identity, and got an answer of 2/cosx=2secx I am doubting that the two equal each other but it is what I keep on getting. Some verification would be much appreciated. Thanks.

how could they NOT be equal, since it is the DEFINITION of sec(x) that sec(x) = 1/cos(x).

YES HAHAHA I FINALLY GOT ONE RIGHT. I RULE!


Oh yes. Where are my manners. Thank you, you sexy quasar you.

By the way the question was an actual question. You know one of those thingys you probably did in high school where they give you something like blah blah blah= blah bla blah and prove it n' such.

That's two you got right.

Lol. I think this is the quickest question ever.

One possible definition. It would be better to say sec(x)cos(x)=1 is a well known identity.

One possible definition. It would be better to say sex(x)cos(x)=1 is a well known identity.

I didn't realize that variables had gender

It would be better to say sex(x)cos(x)=1

sex(x) is by far my favorite trig function, especially when evatuated at the point sex(quasar987).

sex(x) is by far my favorite trig function, especially when evatuated at the point sex(quasar987).

but whenever i put that into my calculator, i keep on getting "no solution."

 

[quasar987]

Hahah. Nice.

Wait I'll think of a come-back.

 

[Knavish]

HAHAHAHA.. this thread is hilarious.

sex(x) is by far my favorite trig function, especially when evatuated at the point sex(quasar987).

It is well known that sex(z) has an essential singularity at z=quasar987 and thus by Picard's Great Theorem sex assumes all values with at most one exception in every neighborhood of z=quasar987. In this case there is one exception. On this darn keyboard x is just left of c. I make that error far less often freehand. At least we know
sex(pi/2-x)=csx(x)
I wonder what sex(x)/csx(x) is. tax(x) or maybe tan^3(x)?

I make that error far less often freehand.

then you might want to consider taking your hand out of your pants once in a while.

Funny how it is defined for sex(Brad Barker + lurflurf) though.

it's defined as "hott." :!)

eww, lurflurf's a guy dude.
