So I have a dummy calculus teacher who is fond of anime and Japan altogether. He gave us pic related task and I can't even understand what he wants us to do in 1b. Can anyone explain in plain english the task?

i guess D = {(x,y) | y = f(x)} but this is beyond retarded

yeah, that's what i thought
but it seems pretty dumb

They're only nips after all.

and what does lies of a curve in this task means?

[Anonymous No.6505615]

A is simple, not quite sure what B is asking though.

no extremas?

[Anonymous No.6505620]

How in the fuck is this a "humanities" problem?

I don't care to look into this, but could it be all points (x,y) for arbitrary values of t? Points (x,y) should still be bounded.

Also what's with all the bullshit? Idk if you're teacher's a dipshit or a cutie. Perhaps offer a cock massage in a cute japanese accent voice

i assume extremas are stationary points and describing the curve is integrating and finding the area of the curve
amirite?

Okay I didn't realize this had t's in A. Normally I'd just take the derivative and set equal to 0 but I don't really know how to deal with this.

I feel tempted to deal with it like a parametric equation but there is no x(t) and y(t). Also a part of me wanted to take the partial derivative with respect to t and set equal to 0 but I think that's wrong too.

Don't overthink it; the problem itself says that it's pre-college-level stuff.

>D contains all points P that lie on the curve y(x)
Set t to different values, and see what you get. D is just the graph defined by the function y(x) for different values of t.

No matter what t is, some things will always be true about that function. State what those things are.

You do A the same way as normal. Just do a partial derivative in t.

>extremas
Extrema is the plural of extremum.

Oh, that is right? I thought partial with respect to t and solve as normal extrema problem might work but I wasn't sure.

This doesn't sound like
>pre-college level stuff
if it involves partial derivatives then again maybe things are different in Asia.

This is fundamentally no different.
You still take the derivative of the function with respect to t only now you'll end up with a function of X as the local extrema.
