I have this equation right here and it turns out both sides are 0 would that mean that the proof is true then?

What do you mean, "both sides are 0"?

they aren't identically zero tho

acoustic sparrow What do you mean, "both sides are 0"?

When i started doing work on them i ended up getting 0/sin^2(x)

Show that work.

Ok

#

Give me a moment

#

#

Basically im proving this is true

#

But i dont really understand how itd be true

#

Sorry i left a little context out of this

#

your +cos is a minus cos

#

should be -cos(x)

#

Wait how so

(rightmost summand in the last numerator)

#

Ok lemme expand my math so i can understand it instead of skipping steps

#

#

bitter citrus Wait how so

Because it's 1 - cos(x) - (1 + cos(x)).

Oh no way

#

😂

acoustic sparrow Sep 21, 2022, 4:13 AM

#

Yeah.

No problem.

bitter citrus Thanks guys

Just for future reference, if you're subtracting two fractions whose denominators are the same, the only way to get 0 is if the numerators are the same.
