The exact values of the six trigonometric functions for the point (x, y) = (20, 21) are listed below:
sin θ = 21 / 29, cos θ = 20 / 29, tan θ = 21 / 20, cot θ = 20 / 21, sec θ = 29 / 20, csc θ = 29 / 21
<h3>How to determine the exact six trigonometric functions related to a point in rectangular format</h3>
Points in rectangular format are points of the form (x, y), where x and y represent the position of the point respect to the origin and along the respective orthogonal axis.
The line segment between the origin and that point represents the hypotenuse of a right triangle. Then, we can determine the six trigonometric functions by using the following formulae:
sin θ = y / √(x² + y²)
cos θ = x / √(x² + y²)
tan θ = y / x
cot θ = x / y
sec θ = √(x² + y²) / x
csc θ = √(x² + y²) / y
If we know that x = 20 and y = 21, then the exact values of the trigonometric functions are:
sin θ = 21 / √(20² + 21²)
sin θ = 21 / 29
cos θ = 20 / √(20² + 21²)
cos θ = 20 / 29
tan θ = 21 / 20
cot θ = 20 / 21
sec θ = √(20² + 21²) / 20
sec θ = 29 / 20
csc θ = √(20² + 21²) / 21
csc θ = 29 / 21
