Calculus
 R
Calculus answers two main questions about functions. (1) How steep is a function at a point? (2) What is the area under the graph over some region?
The first question is answered using the derivative and to answer the second question we use the integral.

Line
 R
A point is nothing more than a location in space. It is zerodimensional. From here we can create a onedimensional object called a line by stringing an infinite number of points along a particular dimension.

Logarithm
 R
By definition, when we say log base b of x equals y, that's the same thing as saying "b to the y equals x".
So if you want to find log base b of x, you're asking "what power do you have to raise b to in oder to get x?"

Plane
 R
By stringing an infinite number of lines along a dimension perpendicular to the line, a twodimensional object called a plane can be obtained. And then if we string an infinite number of planes in either direction, we get three dimensional space.
