Hey guys, I'm not the greatest at math so be nice with this one. Only started doing basic algebra recently at my local tech school in hopes of getting a degree somewhere down the line. Searched 'science and math board' in Google and this was the first result to come up.

I have this:

-sin(x+4)/cos(x+4)

Can the x+4 cancel out, or can this be simplified at all?

Thanks in advance,

Rob

Im pretty sure it can't, since the sin and cos symbols can't be put on their own in a calculator, therefore it wouldn't work on paper. Is this right?

-tan(x+4)

You forgot pic unrelated.

We are all gonna discuss you're panda now.

Thanks. How did you get that? I'd love to learn the processes and not just have the answer.

What if more stuff was on each line, where would the -tan(x+4) go? Example, 3x * -sin(x+4)/cos(x+4)

Sorry, I don't know the general etiquette of this place.

Oh what a cute panda. We should totally save them from going extinct.

Guys can we please stick to the topic. This is just a sample picture that came with my computer. My teacher said the internet was a good resource for extra study, and I'm hoping to get a thing or two out of it.

n := x + 4
-(sin(n)/cos(n))
-(tan(n)) <- Identity
-tan(x+4)

>> No.4371003

>>4370995
Thanks for the response. I remember learning about identities.

What about the other question? Where does the tan get put if the fraction has more in it?

>> No.4371011

>>4371003
It doesn't matter if more is in the argument of tan. If you get confused, define a new variable that entails everything in the argument (bracket). So if it's tan(x^2 + 4x + 44 ln x), just define n := x^2 + 4x + 44 ln x, and do it with your new variable.

Like hell they're not. It's an easy mistake to make, they look so similar.

Pic related, what pandas really look like.
