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.

Isosceles triangle | R
A tiangle with two equal sides.

Line | R
A point is nothing more than a location in space. It is zero-dimensional. From here we can create a one-dimensional 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?"

Logarithm | R
Or you can say, if I raise b to the power of y, I'm going to get x. a + b = c; c - b = a; a × b = c; c ÷ b = a; a ^ b = c; The bth root of c is a. The log base a of c is b.

Partial derivative | R
(1) partial derivative of f with respect to x, f sub x, partial f over partial x. (2) f sub xx, partial squared f over partial x squared. (3) f sub xy, partial squared f over partial y partial x.

Plane | R
By stringing an infinite number of lines along a dimension perpendicular to the line, a two-dimensional 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.

Point | R
A point is nothing more than a location in space. It is zero-dimensional. From here we can create a one-dimensional object called a line by stringing an infinite number of points along a particular dimension.

Scalene triangle | R
A tiangle whose three sides are different lengths.

Space | R
By stringing an infinite number of lines along a dimension perpendicular to the line, a two-dimensional 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.

ε δ definition of limit | R
The limit of f(x) as x approaches a equals L if and only if for any ε>0 there exists a δ>0 such that 0 < | x - a | < δ => | f(x) - L | < ε
