Basically, it IS a curve.
circle, compound curve, elipse . . . .
The reaction described by curve B is occurring with a catalyst.------Apex <('-'<)
The liquid curve is called a meniscus.
zigzag lines, vertical lines, horizontal lines, right curve, over curve,left curve, under curve, scallop lines, left slanting lines, right slanting lines
It is a local maximum for a non-linear curve, which may be a periodic curve.
a poloygon that does not curve or cross and is closed
The definition of a node as it is used in math is that a node is a singular point of a curve. It is also defined as vertex in a graph.
It is the distance, from any point on a curve, to the centre of curvature at that point.
In math, the same as taking the derivative - basically, finding the slope of a line or curve.
It is a straight line joining two different points on a curve which does not cross the curve between those two points.
Here is a video showing more complex graphing of a cosine curve. He has many great videos that you should check out if you need math help.
The Greek letter Kappa (κ) is sometimes used in math. For example, in differential geometry, the curvature of a curve is given by κ.
Even numbers, Equilateral triangle, Exponential growth curve...
I am not quite sure what the meniscus is in math, but I do know what it is defined as when related to science. The meniscus when talking about science is the curve in a flask or other measuremnt jar in the metric system of the liquid. (the curve of the liquid wether it be up or down is the meniscus, although it is more commonly seen going in a downwards direction)
A chord is a line segment between two points on a given curve. Basically it's two points that are connected with a line which all happens to be on a curve. Most likely a circle
That's a point where the curve of a graph changes from "concave upward" to "concave downward", or vice versa.
