one is straight and one is curved simple
the answer
What is the difference between a trend line and a line of best fit
budget line shows purchasing power of an consumer but indifference curve show willingness of consumer for two commodities.
The tangent line is the instantaneous rate of change at a point on a curve. The secant line crosses a curve twice at points A and B, representing the average rate of change between those two points.
Linear is a straight line and non linear could be a curve or anything but a straight line
Between the two point line to say that is both a curve and there are clear.
If you take two distinct points on a curve, the arc is the part of the curve connecting the two points while the chord is the straight line connecting them.
Regression techniques are used to find the best relationship between two or more variables. Here, best is defined according to some statistical criteria. The regression line is the straight line or curve based on this relationship. The relationship need not be a straight line - it could be a curve. For example, the regression between many common variables in physics will follow the "inverse square law".
Curvature :act of curving, state of being curved; measure of the degree of a curve in a line. Curve:line that is not straight, continuously bending line; bend, turn (in a road) Reference: babylon Dictionary
Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
Yes there is a large difference between the two. A line has no end and a line segment ends.
