# Mechamath

Mechamath is a website that offers various resources for the study of mathematics. Our goal is to help students learn math in an accessible way.

## ALGEBRA

Learn about variables, equations, functions and more advanced algebraic topics.

#### Algebraic expressions

Algebra is a branch of mathematics where numbers and letters are used to represent numeric problems

#### Linear equations with one variable

Equations are linear when they can be written in the form *ax+b=c, *where, *x* is a variable and *a, b* and *c* are constants.

#### Laws of exponents

#### Domain and range of functions

The domain is the set of possible values for the inputs of the function. The range is the set of possible values for the outputs.

## GEOMETRY

Learn about angles, perimeter, area and volume of different geometric figures.

#### Properties of a parallelogram

A parallelogram is a two-dimensional figure that has sides that are parallel to each other.

#### Corresponding angles

#### Elements of a sphere

Some of the most important elements of the spheres are the radius, the diameter, the center, the poles and the chords.

#### Nets of a cube

## TRIGONOMETRY

Learn about angles in a triangle, trigonometric functions and trigonometric identities.

#### Period of the cosine function

#### Amplitude of sine functions

#### Rectangular to polar coordinates

Polar coordinates are written in the form (*r, θ*), where *r* is the distance and θ is the angle.

#### Law of cosines

The law of cosines is the ratio of the lengths of the sides of a triangle with respect to the cosine of its angle.

## PRECALCULUS

Learn about parabolas, ellipes, circumferences and hyperbolas.

#### Circumference with center at origin

#### Elements of a parabola

#### Equation of an ellipse with examples

Equations of ellipses centered at the origin can have two variations depending on their orientation.
