Functions provide a powerful tool for modeling real-world phenomena, such as population growth, projectile motion, and financial investments.

Equations

Equations are mathematical statements that equate two expressions, and the book covers various methods for solving equations, including:

• Solving linear equations: using inverse operations, substitution, and elimination
• Solving quadratic equations: using factoring, completing the square, and the quadratic formula
• Solving higher-order equations: using numerical methods, such as the Newton-Raphson method
• Solving systems of equations: using substitution, elimination, and matrices

Equations are used extensively in solving real-world problems, such as finding the roots of a polynomial, determining the break-even point in economics, and calculating the trajectory of a projectile.

Matrices provide a concise and efficient way to represent and manipulate systems of linear equations, and they are widely used in various fields, such as engineering, physics, and economics.

Trigonometric Functions

Trigonometric functions are mathematical functions that relate the angles of a right triangle to the lengths of its sides. They are used extensively in various fields such as navigation, surveying, engineering, and astronomy.

The fundamental trigonometric functions are sine, cosine, tangent, cotangent, secant, and cosecant. These functions are defined as follows:

• Sine (sin): The ratio of the length of the opposite side to the length of the hypotenuse.
• Cosine (cos): The ratio of the length of the adjacent side to the length of the hypotenuse.
• Tangent (tan): The ratio of the length of the opposite side to the length of the adjacent side.
• Cotangent (cot): The ratio of the length of the adjacent side to the length of the opposite side.
• Secant (sec): The ratio of the length of the hypotenuse to the length of the adjacent side.
• Cosecant (csc): The ratio of the length of the hypotenuse to the length of the opposite side.

Trigonometric functions have many important properties, including:

• They are periodic functions, which means that they repeat their values at regular intervals.
• They are symmetric functions, which means that they have the same values for certain angles.
• They can be used to solve a variety of problems, such as finding the height of a building or the distance to a star.

Trigonometric functions are represented graphically using a unit circle. The unit circle is a circle with a radius of 1. The coordinates of a point on the unit circle are (cos θ, sin θ), where θ is the angle between the positive x-axis and the line connecting the point to the center of the circle.

Trigonometric functions can also be represented using tables. Tables of trigonometric functions are available in many textbooks and online resources.
