Best Answer

sin = sqrt(1 - cos^2)tan = sqrt(1 - cos^2)/cos

sec = 1/cos

cosec = 1/sqrt(1 - cos^2)

cot = cos/sqrt(1 - cos^2)

What does trigonometric identities all about?

They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.


Can this be used for sines?

No. Sines are well defined trigonometric ratios whereas "this" is not defined at all.


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.)


Uses of six trigonometry functions?

The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.


What is trigonometric identities?

Just as with any other identity, a trigonometric identity is a trigonometric statement (other than a definition), which is true for all values of the variable or variables.


Csc x tan x?

If you want to simplify that, it usually helps to express all the trigonometric functions in terms of sines and cosines.


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.

Are all trigonometric functions periodic?

yes.


Is all trigonometric functions are periodic?

Yes.


Are all ratios a fraction?

All ratios can be written as fractions.


Why are there six trigonometrics functions only?

All the trigonometric functions are derived from the right angled triangle. If we consider the three sides (AB, BC, CA) of a triangle and the included angle. There is a possibility of getting six functions based on the ratios like AB/AC, BC/AC, AB/BC, BC/AB, AC/BC, AC/AB . So we will have six trigonometric functions
