What trigonometric ratios cannot be greater than one?
Sine and cosine.
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.
How many trigonometric ratios are there?
Six.
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 is six trigonometric ratios of 45 degrees?
sin(45) = cos(45) = 1/sqrt(2) tan(45) = cot(45)= 1 csc(45) = sec(45) = sqrt(2)
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?
For angles between 90 and 180 use the angle (180 - X) For angles between 180 and 270 use (X - 180) For angles between 270 and 360 use (360 - X) For angles greater than 360 subtract 360 until the angle is between 0 and 360 degrees and one of the above rules can be applied. You need to be careful with the signs of the ratios.

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.
How did people measure the height of Mt Everest?
Trigonometric ratios.
