Need help with a small vector and parametric question.

In summary, a vector is a mathematical quantity with both magnitude and direction, represented by an arrow. A parametric equation is a way of representing functions using parameters. To find the magnitude of a vector, you use the Pythagorean theorem. A unit vector has a magnitude of 1 and is used to indicate direction without changing the magnitude. Parametric equations can be converted to vector form using the parameter as the vector's components.

2. Determine vector and parametric equations for the z-axis. (Just so everyone is clear, The z-axis is actually a line in space. So you need to write the vector and parametric equation of this line)

This should be posted in the homework forum along with whatever work you have tried on the problem so far (see the template that pops up when you make a thread)

Do you know what "vector" and "parametric" equations mean?
 

1. What is a vector?

A vector is a mathematical quantity that has both magnitude (size) and direction. It is represented by an arrow pointing in the direction of the vector, with the length of the arrow representing the magnitude.

2. What is a parametric equation?

A parametric equation is a way of representing a set of equations or functions using one or more independent variables, called parameters. It allows us to describe a curve or surface in terms of its coordinates in terms of these parameters.

3. How do you find the magnitude of a vector?

To find the magnitude of a vector, you use the Pythagorean theorem. You square the x and y components of the vector, add them together, and then take the square root of the sum.

4. What is a unit vector?

A unit vector is a vector with a magnitude of 1. It is used to indicate direction without affecting the magnitude of a vector. Unit vectors are often used in physics and engineering calculations.

5. How do you convert parametric equations to vector form?

To convert parametric equations to vector form, you can use the parameter as the variable for the vector components. For example, if the parametric equations are x = t and y = 2t, the vector form would be x = t, y = 2t. This allows for easier manipulation and calculation of the equations.
