A TRIGONOMIC ratio is a ratio between either the opposite side of an angle and the hypotenuse of a triangle (sine), the adjacent side of an angle and the hypotenuse of a triangle (cosine), or the opposite side of an angle and the adjacent side (tangent).

What is the trigonometric ratio for Cos?
the adjacent side over the hypotenuse
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
What name is given to the ratio of the length of the side opposite 30 degree to the length of hypotenuse?
There is no particular name for the trigonometric ratio which depends on the measure of a specific angle.
How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
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.
The trigonometric ratio cosine is equal to?
opposite over adjacent
What is the trigonometric ratio for Cos?
the adjacent side over the hypotenuse
Does your cosine like somebody?
A cosine is a trigonometric ratio and is not capable of liking or disliking anything!
The trigonometric ratio that compares the opposite side length to the adjacent side length is what?
tangent
What is cos 22?
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
What is cos(22 degrees)?
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
What name is given to the ratio of the length of the side opposite 30 degree to the length of hypotenuse?
There is no particular name for the trigonometric ratio which depends on the measure of a specific angle.
The trigonometric ratio that compares the opposite side going to the hypotenuse is a SINE b TANGENT c Cosine?
a) sine
How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
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.
How do you plot a trigonometry graph?
You plot the magnitude of the angle along the horizontal axis and the value of the trigonometric ratio on the vertical axis.
