What trigonometric ratios cannot be greater than one?
Sine and cosine.
How do you calculate the right angle triangles angles?
To calculate the angles of a right triangle, you can use trigonometric ratios: sine, cosine, and tangent. For a triangle with an angle ( A ), you can find the sine (( \sin A )), cosine (( \cos A )), or tangent (( \tan A )) based on the lengths of the opposite, adjacent, and hypotenuse sides. Additionally, you can use the inverse trigonometric functions (arcsin, arccos, arctan) to find the angles given the lengths of the sides. Remember that the sum of the angles in any triangle equals 180 degrees, so if you know one angle is 90 degrees, the other two angles will sum to 90 degrees.
What is trigonometry all about?
The word, trigonometry" is derived from trigon = triangle + metry = measurement. It is based on the study of angles of a triangle and their properties. Although trigonometric ratios are often introduced to students in the context of triangles, their properties for all angles.For example, trigonometric functions are well defined for angles with negative values as well as for more than 180 degrees even though no triangle can possibly have angles with such measures.
What calculation is different in finding missing side lengths and angle measures in a right triangle using the trigonometric functions?
When finding missing side lengths in a right triangle using trigonometric functions, you typically apply ratios like sine, cosine, or tangent, which relate the angles to the lengths of the sides. Conversely, when calculating missing angle measures, you use the inverse trigonometric functions (such as arcsine, arccosine, or arctangent), which take the ratios of the sides and return the corresponding angles. Thus, the key difference lies in using direct ratios for side lengths and inverse functions for angles.
How many trigonometric ratios are there?
Six.
Why do similar triangles have the same trigonometric ratios?
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
What complements tan 132 degree angle?
Complements are defined for angles, not trigonometric ratios of angles.
Does a rectangular prism have any secants?
Yes, since it has vertices it has angles and since it has angles it has trigonometric ratios
What trigonometric ratios cannot be greater than one?
Sine and cosine.
What angles are used to relate the values returned by inverse trigonometric functions to angles larger than 90 degrees?
When using inverse trigonometric functions to relate values to angles larger than 90 degrees, we typically use reference angles. Reference angles are acute angles formed between the terminal side of the angle in question and the x-axis. By using reference angles, we can determine the appropriate quadrant and sign for the angle, allowing us to accurately relate the values returned by inverse trigonometric functions to angles greater than 90 degrees.

How do you find the angles of a triangle when you are given ratios?
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
What does trigonometric identities all about?
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
Why do trigonometric ratios do not depend on the size of the right triangle?
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
What is the use of complement and supplement angle degrees minutes seconds used for?
There are two main uses. One is, in a complicated shape, to find the measure of an unknown angle using known values of other angles. The other is that trigonometric ratios are related to their supplement angles. Also, the sine of an angle is related to the cosine of of its complement.
What are the connections between right triangle ratios trigonometric functions and the unit circle?
Right triangle ratios serve as the foundation for defining trigonometric functions such as sine, cosine, and tangent, which relate the angles of a triangle to the lengths of its sides. The unit circle, a circle with a radius of one centered at the origin of a coordinate plane, extends these concepts by allowing trigonometric functions to be defined for all angles, not just those in right triangles. In the unit circle, the x-coordinate corresponds to the cosine of the angle, while the y-coordinate corresponds to the sine, thus linking the geometric representation of angles to their trigonometric values. This connection facilitates the understanding of periodic properties and the behavior of trigonometric functions across all quadrants.
