The domain of the sine function is (-∞,∞) and its range is. Unlike the definitions of trigonometric functions based on right triangles, this definition works for any angle, not just acute angles of right triangles, as long as it is within the domain of sin(θ). Meaning that the y-value of any point on the circumference of the unit circle is equal to sin(θ). Thus, we can use the right triangle definition of sine to determine that The terminal side of the angle is the hypotenuse of the right triangle and is the radius of the unit circle. θ is the angle formed between the initial side of an angle along the x-axis and the terminal side of the angle formed by rotating the ray either clockwise or counterclockwise. In such a triangle, the hypotenuse is the radius of the unit circle, or 1. Given a point (x, y) on the circumference of the unit circle, we can form a right triangle, as shown in the figure. The unit circle definition allows us to extend the domain of trigonometric functions to all real numbers. The right triangle definition of trigonometric functions allows for angles between 0° and 90° (0 and in radians). A unit circle is a circle of radius 1 centered at the origin. Trigonometric functions can also be defined as coordinate values on a unit circle. A wheel chair ramp needs to have an angle of 10° and a rise of 3 feet, what is the length of the ramp? ![]()
