Find a parameterization for each of the following curves.
a. The straight line segment from (3,2) to (-1,1).
b. The curve from (3,-8) to (-2,-3).
I have no idea how to do this problem. Looks like a basic problem but I have no idea what parameterization means. Any help is appreciated!
A parameter or a curve is an additional variable, t, say such that both x and y are written in terms of that variable. Any one-dimensional object, such as a curve, can be written in terms of 1 parameter, any two-dimensional object, such as a surface, can be written in terms of two parameters. In effect, that's what "dimension" means.
But as long as y is a function of x, we can use "x" itself as parameter.
If we can take , with .
