What trigonometric ratios cannot be greater than one?
Sine and cosine.
How do you find trigonometric ratios without a calculator?
There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)
When would you use the law of sines or law of cosines instead of a trigonometric ratio?
Trigonometric ratios, by themselves, can only be used for right angled triangles. The law of cosines or the sine law can be used for any triangle.
Examples of the three basic trigonometric ratios?
Given a unit circle (radius = 1) and a counterclockwise angle (theta) between the positive x axis, with the x-y coordinate of the point on the circle that the angle intersects, the three basic trigonometric ratios are... 1. sine (theta) is y 2. cosine (theta) is x 3. tangent (theta) is x / y
What does trigonometric ratios mean?
They may be defined as the ratios of the lengths of sides of a right angled triangle, relative to either of the other angles.sine = opposite/hypotenusecosine = adjacent/hypotenusetangent = opposite/adjacentcosecant = hypotenuse/oppositesecant = hypotenuse/adjacentcotangent = adjacent/opposite.
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 does trigonometric identities all about?
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
How did people measure the height of Mt Everest?
Trigonometric ratios.
What is the difference between a tangent and a secant?
They are different trigonometric ratios!
What the three main trigonometric ratios mean?
sin, cos and tan
What trigonometric ratios cannot be greater than one?
Sine and cosine.
Explain how distances can be found using a right triangle?
Using trigonometric ratios.
Can this be used for sines?
No. Sines are well defined trigonometric ratios whereas "this" is not defined at all.
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

How do you choose the sides in trigonometry?
We take side to take trigonometric ratios according 2 the vertex of triangle which is given.
