evaluate the following limit by interpreting it as a derivative:
lim (theta-->pi/3) of (secx-2)/(x-pi/3)

>secx-2
Kids should be taught proper notation.
It can be <span class="math">\sec(x)-2[/spoiler] or <span class="math">\sec(x-2)[/spoiler], but the tard won't tell until someone already wastes his time helping him.
Not like I'm going to help - I'm not even going to link you to the site which would solve it for you.
Because you are a faggot.

Order of operations you retard.

secx-2 = sec(x) - 2
It's implied.

No it isn't. Either interpretation is valid.

>>2589265

All you did was put parenthesis around the x? That's like saying 2(x) is different than 2x.

This thread is over.

/Thread.

Thank you.

No.

The guy goes, using your example, 2x-2.

The other anon goes "DERP, is that 2(x-2) or 2x - 2?"

>> No.2589591

>>2589314

You are making no sense and contradicting yourself.

First you said
>secx-2 = sec(x) - 2

To which I said you're retarded because it's just like saying 2(x) or 2x, which is no difference at all.

Then you said
>The guy goes, using your example, 2x-2.
>2(x-2) or 2x - 2?
And I have no idea where this came from because I never said it.

From what you said earlier, it's just like saying
2(x)-2 or 2x - 2

There's no difference, what the fuck are you trying to say?
