Name of a point on a curve?

[FrostedNipple]

I need to describe something, and i don't know how to word it or the proper word to word, WORD!




The point i have circled in red, what word would you give to the very most bottom point of that anti-peak?

 

[BlackDragon]

Lowest point of the whole line = Global minima
Highest point of the whole line = Global maxima

Lowest point locally = Local minima
Highest point locally = Local maxima

 

[snail1]

(local) minimum

 

[Tefal]

"this bit here"

 

[archer_dan]

or, if its wave it'd be a trough

 

[fini]

The bit circled in red below the displeased face

 

[Zip]

Apex?

 

[FrostedNipple]

How do i describe it if i can't circle it?

 

[fini]

Point "a" - then draw a line to it with the letter "a"

 

[Cew27]

in waves there are troughs and peaks, troughs being lowest point

i used 'local minima of the outer oscillation' they were being described as oscillations in the text. thanks

 

[DarkShadow]

Curve?

 

[Dave]

(local) minimum

This.

'Outer' could be the left or right one and is thus vague.

'Outer' could be the left or right one and is thus vague.

what i'm talking about could be the left of right, it's not shown well in my picture but it is supposed to be symettrical.

What is it ? It looks a bit like a potential energy surface to me.

Presumably you have axes so you could refer to it as the local minimum at x = whatever

 

[FrostedNipple]

it's coursework, so i'm not going to say incase they try to do me for plagerism

Eric?

Or Alan?
