 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. http://qindex.info/d.php?c=5079#5210

 Cross Product | R Given two nonzero vectors in two or three dimensions, their cross product is a vector with magnitude equal to the product of the magnitudes of the vectors times the sine of the angle between the vectors and direction perpendicular to the vectors. http://qindex.info/d.php?c=5079#5291

 Dot Product | R Given two nonzero vectors in two or three dimensions, their dot product is the product of the magnitudes times cosine of the angle between the two vectors. http://qindex.info/d.php?c=5079#5288

 Goldbach conjecture | R Every even number is the sum of two primes. In the nearly 300 years since the conjecture was formulated, nobody has ever proved it. http://qindex.info/d.php?c=5079#3745

 Greek Alphabet | R Α α Β β Γ γ Δ δ Ε ε Ζ ζ Η η Θ θ Ι ι Κ κ Λ λ Μ μ Ν ν Ξ ξ Ο ο Π π Ρ ρ ϱ Σ σ/ς Τ τ Υ υ Φ φ Χ χ Ψ ψ Ω ω http://qindex.info/d.php?c=5079#5203

 Iff | R If and only if http://qindex.info/d.php?c=5079#3408

 Integration | R The Fundamental Theorem of Calculus: Redefining Integration http://qindex.info/d.php?c=5079#3658

 Limit | R The limit of f of x as x approaches a is L. http://qindex.info/d.php?c=5079#3473

 Line | R We can create a one-dimensional object called a line by stringing an infinite number of points along a particular dimension. http://qindex.info/d.php?c=5079#5177

 Linear systems | R A collection of 2 or more linear equations http://qindex.info/d.php?c=5079#3810

 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?" http://qindex.info/d.php?c=5079#5065

 Logarithm | R "The base of the log raised to the power of what's on the other side of the equal sign will equal the number that the log is operating on." http://qindex.info/d.php?c=5079#5356

 Matrix | R A rectangular array of numbers http://qindex.info/d.php?c=5079#3811

 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. http://qindex.info/d.php?c=5079#5077

 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. http://qindex.info/d.php?c=5079#5031

 Point | R A point is nothing more than a location in space. It is zero-dimensional, meaning that it has no dimensions of any kind. We represent points with dots and some capital letter. http://qindex.info/d.php?c=5079#5030

 Prime number | R A prime number is a natural number greater than 1 that is devided only by 1 and itself. http://qindex.info/d.php?c=5079#3621

 Prime number theorem | R The number of prime numbers less than a certain natural number is asymptotically equivalent to x/ln(x). http://qindex.info/d.php?c=5079#3709

 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. http://qindex.info/d.php?c=5079#5178

 Transformation | R Symetry, transformation, translation, rotation, reflection, dilation, congruent http://qindex.info/d.php?c=5079#3856

 Triangle classification | R Triangles can be classified by their angles and sides: scalene, isoscelese, equilateral, acute, right, abtuse. http://qindex.info/d.php?c=5079#5212

 Trigonometric Functions | R Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent http://qindex.info/d.php?c=5079#3457

 Vector | R A mathematical construct that has both magnitude and direction http://qindex.info/d.php?c=5079#3815
