Can a linear line be curved?

A cautionary note: Economists are accustomed to designate all lines in graphs as curves – both straight lines and lines which are actually curved. Although the slope of a linear function is the same no matter where on the line it is measured, the slope of a non-linear function is different at each point on the line.

Can a straight line have a non zero curvature?

straight lines have zero curvature; circles have constant curvature.

What is a straight curve?

Straight Line Curved Line. The shortest line joining any 2 points is a straight line. If a point moves in only one direction, we get a straight line. A line that is not straight is a curved line. If a point does not move in one direction, we get a curve.

What is straight line math?

What is a Straight Line? A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.

Does a straight line represent a function?

No, every straight line is not a graph of a function. Nearly all linear equations are functions because they pass the vertical line test.

Do cylinders have curvature?

For a cylinder of radius r, the minimum normal curvature is zero (along the vertical straight lines), and the maximum is 1/r (along the horizontal circles). Thus, the Gaussian curvature of a cylinder is also zero. In differential geometry, it is said that the plane and cylinder are locally isometric.

Is line segment a curve?

We know when two lines meet we get a point. When two points on a plane surface are joined, a straight line segment is obtained. But if two points in a curved surface is joined, a curved line segment is drawn. When a line segment is extended towards both sides unlimitedly it becomes a line.
