Trigonometric functions are mathematical expressions that relate the angles of a triangle to the lengths of its sides. The three main trigonometric function are:
- Sine: The ratio between the lengths of the sides opposite to the angle and the hypotenuse.
- Cosine (cos): The ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
- Tangent (tan): The ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
Trigonometric identities, on the other hand, are equations involving trigonometric functions that hold true for all angles. These identities are powerful tools to simplify expressions, solve equations and prove mathematical statements. Some commonly used identities include:
Pythagorean identity: sin2nd + cos2nd = 1
Reciprocal Identifications: cscth=1/sinth; secth=1/costh; cotth=1/tanth
Quotient Identities: tanth = sinth/costh, cotth = costh/sinth
Cofunction Identities: sin(p/2 - th) = costh, cos(p/2 - th) = sinth, tan(p/2 - th) = 1/tanth
The unit circle is a fundamental tool in trigonometry that relates the angles of triangles to the coordinates of points on a circle with a radius of 1. It allows us to visualize and solve trigonometric problems more effectively. This is a visual representation of the unit circle.

Analytic Geometry, Coordinate Systems and Bridging Algebra with Geometry
In the realm of mathematics, the fusion of algebra and geometry gives rise to Analytic Geometry, a powerful tool for understanding and visualizing mathematical concepts. Analytic Geometry introduces Coordinate Systems. This allows us to graph equations using the coordinate plane, find slopes and intersects, and solve mathematical problems.
We can discover hidden relationships between geometric and algebraic concepts by displaying algebraic equations in a coordinate system. This bridge between algebra and geometry helps us gain deeper insight into mathematical phenomena, and solve many problems with precision.
Dr. Emily Johnson is a well-known mathematician who says that Analytic Geometry offers a powerful framework to analyze geometric shapes and the algebraic properties underlying them. It offers an elegant way to understand the interaction between geometry and algebra, providing a visually intuitive representation of mathematical concepts.
In Analytic Geometry, we work with two-dimensional coordinate systems, often referred to as the Cartesian coordinate system. This system consists of a horizontal x-axis and a vertical y-axis, intersecting at a point called the origin (0, 0). By assigning coordinates to points on the plane, we can graph equations and explore the relationships between variables.
Graphing Equations
By graphing equations, we can visualize mathematical patterns and relationships. We can plot points on the coordinate plane and connect them to show linear equations, quadratic function, and other algebraic expressions.
| Equation | Graph |
|---|---|
| y = 2x + 1. | [Graph of the linear equation] |
| x^2 + y^2 = 4 | [Graphic of the circle equation] |
| y = sin(x). | [Graph of the sine function] |
By visually analyzing these graphs, we can uncover key properties of the associated equations, such as slope and y-intercept for linear equations, symmetry and center for conic sections, and periodic behavior for trigonometric functions.
Find slopes and intercepts
The slopes and intercepts are essential to understanding linear relationships. In Analytic Geometry we can calculate the slope of a straight line by dividing the difference in y by the difference in x at any two points along the line. The yintercept is the point at which the line intersects with the y axis.
The x intercept is the point at which the line intersects with the x axis. These geometric interpretations provide valuable insights into the behavior and characteristics of linear equations.
Analytic Geometry Applications
Analytic Geometry has many applications in physics, engineering and computer science. Analytic Geometry can be used to solve real-world problems.
"Analytic Geometry equips us with a powerful set of tools for analyzing and solving complex problems that involve both algebraic and geometric considerations," adds Dr. Johnson.

- Cosine (cos): The ratio of the length of the side adjacent to an angle to the length of the hypotenuse.
- Tangent: The ratio of the width of a side to that of a side next to an angle.
The Pythagorean Theorem:
The Pythagorean theory allows us to determine the length of the third angle of a triangle if we know the lengths of its other two angles. The Pythagorean theorem states that the square of the hypotenuse length in a triangle is equal to the total of the squares for the lengths of both sides.
To better understand how trigonometry is applied to solve geometric problems, let's consider an example:
Exemple: If you have a triangle of a right angle with the hypotenuse known, then you must find the lengths for the two other sides.
By using trigonometric ratios, you can determine the relationship between the angles and the sides of the triangle and solve for the missing lengths.
Trigonometric Ratios for Common Angles
| Angle | Sine | Cosine | Tangent |
|---|---|---|---|
| 0deg | 0 | 1 | 0 |
| 30deg | 1/2 | 3/2 | 3/3 |
| 45deg | 2/2 | 2/2 | 1 |
