2. The Initial Encounter: Geometry and Right Triangles
2.1. Introduction to Trigonometry in Geometry
The first formal introduction to sin, cos, and tan typically occurs in high school geometry courses, specifically when students begin to study right triangles. A right triangle is defined as a triangle containing one angle of 90 degrees.
2.2. Key Concepts: Angles and Sides of Right Triangles
In the context of right triangles, trigonometry is used to relate the angles and the lengths of their sides. The three primary trigonometric ratios—sine, cosine, and tangent—are each defined as a ratio of two sides of a right triangle relative to one of its acute angles (an angle less than 90 degrees).
- Sine (sin): The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
- Cosine (cos): The cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
- Tangent (tan): The tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
2.3. The Mnemonic: SOH CAH TOA
A useful mnemonic to remember these ratios is SOH CAH TOA:
- SOH: Sine = Opposite / Hypotenuse
- CAH: Cosine = Adjacent / Hypotenuse
- TOA: Tangent = Opposite / Adjacent
This mnemonic serves as a quick reference, helping students recall the definitions of the trigonometric functions when solving problems involving right triangles.
3. Expanding Horizons: Algebra II and Trigonometric Functions
3.1. Extending the Concepts in Algebra II
After geometry, students usually encounter trigonometric functions again in Algebra II. In this course, the focus shifts from right triangles to the broader concept of trigonometric functions defined on the unit circle.
3.2. The Unit Circle: A Foundation for Trigonometry
The unit circle is a circle with a radius of one, centered at the origin of a coordinate plane. It provides a way to define trigonometric functions for any angle, not just those in a right triangle.
- Sine (sin): On the unit circle, the sine of an angle is the y-coordinate of the point where the terminal side of the angle intersects the circle.
- Cosine (cos): The cosine of an angle is the x-coordinate of the point where the terminal side of the angle intersects the circle.
- Tangent (tan): The tangent of an angle is the ratio of the y-coordinate to the x-coordinate (y/x). It can also be understood as sin(θ) / cos(θ).
3.3. Radian Measure: A New Way to Measure Angles
In Algebra II, students also learn about radian measure, which provides an alternative way to measure angles. One radian is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
- Conversion: To convert degrees to radians, multiply by π/180. To convert radians to degrees, multiply by 180/π.
Radian measure is particularly useful in calculus and other advanced mathematics courses because it simplifies many formulas involving trigonometric functions.
3.4. Trigonometric Identities: Tools for Simplification
Trigonometric identities are equations involving trigonometric functions that are true for all values of the variables for which the functions are defined. These identities are used to simplify trigonometric expressions and solve trigonometric equations.
- Pythagorean Identity: sin²(θ) + cos²(θ) = 1
- Reciprocal Identities: csc(θ) = 1/sin(θ), sec(θ) = 1/cos(θ), cot(θ) = 1/tan(θ)
- Quotient Identities: tan(θ) = sin(θ)/cos(θ), cot(θ) = cos(θ)/sin(θ)
Understanding and applying these identities is crucial for advanced problem-solving in trigonometry.

The graphs of sine, cosine, and tangent functions are periodic, meaning they repeat their values at regular intervals. Understanding these graphs is essential for analyzing and modeling real-world phenomena.
- Sine Function (y = sin(x)): The sine function has a period of 2π, an amplitude of 1, and oscillates between -1 and 1.
- Cosine Function (y = cos(x)): The cosine function also has a period of 2π and an amplitude of 1, but it is shifted π/2 units to the left compared to the sine function.
- Tangent Function (y = tan(x)): The tangent function has a period of π and vertical asymptotes at x = (n + 1/2)π, where n is an integer.
4.3. Inverse Trigonometric Functions
Inverse trigonometric functions, such as arcsin, arccos, and arctan, are used to find the angle that corresponds to a given trigonometric ratio. These functions are essential for solving equations where the angle is unknown.
- arcsin(x) or sin⁻¹(x): The inverse sine function returns the angle whose sine is x.
- arccos(x) or cos⁻¹(x): The inverse cosine function returns the angle whose cosine is x.
- arctan(x) or tan⁻¹(x): The inverse tangent function returns the angle whose tangent is x.
4.4. Trigonometric Equations: Solving for Unknown Angles
Trigonometric equations involve trigonometric functions and require solving for the unknown angle. These equations can be solved using algebraic techniques, trigonometric identities, and inverse trigonometric functions.
4.5. Trigonometry in Calculus
In calculus, trigonometric functions are used extensively in differentiation and integration. Understanding the derivatives and integrals of trigonometric functions is crucial for solving many calculus problems.
- Derivatives:
- d/dx (sin(x)) = cos(x)
- d/dx (cos(x)) = -sin(x)
- d/dx (tan(x)) = sec²(x)
- Integrals:
- ∫ sin(x) dx = -cos(x) + C
- ∫ cos(x) dx = sin(x) + C
- ∫ sec²(x) dx = tan(x) + C
These derivatives and integrals are used to solve a wide range of problems in calculus, including finding areas, volumes, and rates of change.
