# Precalculus Tutoring

A "Calculus" is a method for methodically defining a result, for arriving at a conclusion, or for calculating an answer. Precalculus is a program with college level algebra and trigonometry that is intended to prepare students for the study of calculus. Precalculus gives the contextual for the mathematical ideas, problems, notions, issues and practices that appear in calculus, including trigonometry, functions, matrices, complex numbers, vectors, and others.  Students obtain a solid foundation in algebra and trigonometry. Importance is given on understanding the properties of linear, polynomial, exponential, piecewise, trigonometric and logarithmic functions. The term "function" is sometimes understood to mean continuous function, linear function, or function into the complex numbers. Students learn to work with various types of functions in figurative, graphical, numerical and verbal form.

Precalculus mathematics is mathematics that offers circumstantial background for the mathematical concepts, problems, issues and procedures that appear in calculus. Undoubtedly one key related tool for the calculus is the function theory. Being accustomed with function concepts and specific functions provides a significant foundation and language for the calculus.

To understand calculus you should have an experience that consents you to practice
• numbers and variables in the context of algebra,
• equations and functions both algebraically and visibly, and
• real world applications that use functions to relate the quantities involved.

## Pre Calculus Topics

The branch of mathematics that deals with limits and the differentiation and integration of functions of one or more variables is known as Pre-Calculus.

Mentioned below are a few Pre Calculus Topics that are studied in Calculus.
1. Vector: A mathematical object that has both magnitude which can be zero and direction.
2. Range: The set of all values that a function can take. The difference between the minimum and the maximum values of a data set.
3. Domain: The set of values for which a function is defined.
4. Function: A kin that connects members of one set with members of another set.
5. Logarithm: The power to which a number called the base is raised to produce a given number;
e.g., the logarithm of 100 to the base 10 is 2.
6. Ellipse:    A conic section with eccentricity less than one.
7. Complex Number: A number containing a real part and an imaginary part. A complex number is an element of the complex plane.
8. Rational Function: A function that is penned as the quotient of two polynomials.
9. Reflection: The activity of trading all the points of a mathematical entity with their mirror images.
10. Rotation:  The turning or revolving of an object or coordinate system about a fixed point.
11. Determinant: A function that assigns a scalar to a square matrix. The matrix has an inverse if and only if its determinant is nonzero.
12. Tangent Line: A line that does not cross a curve at a given point but touches instead.
