Q:
# What is a derived quantity?

A:
### Quick Answer

**A derived quantity is a quantity that is based on the result of a systematic equation that includes any of the seven basic quantities, which are the kilogram, meter, second, ampere, kelvin, mole and candela.** Examples of derived quantities include area (square meters), speed (meters per second) and frequency (hertz).

Most derived quantities have been assigned special names and symbols because of their complexity of presenting them using base units. An example of this is the newton, which is a unit of force that equates to the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. Two of the derived quantities, the radian and steradian, are dimensionless.

Q:
## How do you find the average velocity in calculus?

A:

Full Answer >**Average velocity is the result of dividing the distance an object travels by the time it takes to travel that far.**The formula for calculating average velocity is therefore: final position - initial position/final time - original time, or [d(1) - d(0)]/[t(1) - t(0)]. Average velocity is expressed as a ratio, such as “miles per hour,” of distance displaced to time in motion.Filed Under: -
Q:
## How did Isaac Newton invent calculus?

A:Calculus was developed independently by both Isaac Newton and Gottfried Leibniz during the later part of the 1600s. For Newton, calculus was primarily a tool he needed for explaining the motion of the planets. It would be difficult to say precisely how he developed his ideas because he was secretive about his methods, but it certainly grew out of his understanding of the laws of motion and acceleration.

Q:
## How hard is precalculus compared to college algebra?

A:

Full Answer >**Precalculus generally uses algebraic concepts taught in college-level algebra, but if there is a strong understanding of algebraic problems, precalculus may not be difficult.**Both forms of mathematics courses involve a significant number of new concepts and whether a person finds one course more difficult than the other depends on the person's strengths as a mathematician.Filed Under: -
Q:
## What is the vector equation of a line?

A:

Full Answer >**The vector equation of a line is r = a + tb.**In this equation, "a" represents the vector position of some point that lies on the line, "b" represents a vector that gives the direction of the line, "r" represents the vector of any general point on the line and "t" represents how much of "b" is needed to get from "a" to the position vector.Filed Under:
