Sine Theta (sin θ) = opposite/hypotenuse = a/c
Cosine Theta (cos θ) = adjacent/hypotenuse = b/c
Tangent Theta (tan θ) = opposite/adjacent = a/b
Cotangent Theta (cot θ) = adjacent/opposite = b/a
Secant Theta (sec θ) = hypotenuse/adjacent = c/b
Cosecant Theta (csc θ) = hypotenuse/opposite = c/a

There are three types of trigonometric functions, they are: 1- Plane Trigonometric Functions 2- Inverse Trigonometric Functions and 3- Hyperbolic Trigonometric Functions
trigonometric table gives the values of all the trigonometric functions for any angle. i.e; it gives the numerical values of sine, cosine, tangent etc for any angle between 0 to 180 degrees the values for other angles can be calculated using these.
In geometry, similar shapes have the same angles. This means that the values of the basic trigonometric functions of these angles are the same.
With ease, I suppose. The question depends on what you consider easy trigonometric functions.
Vectors.

The sine and the cosine are always less than one.

There are several topics under the broad category of trigonometry. * Angle measurements * Properties of angles and circles * Basic trigonometric functions and their reciprocals and co-functions * Graphs of trigonometric functions * Trigonometric identities * Angle addition and subtraction formulas for trigonometric functions * Double and half angle formulas for trigonometric functions * Law of sines and law of cosines * Polar and polar imaginary coordinates.
Vectors.
You can use them to find the sides and angles of a right triangle... just like regular trigonometric functions
There r 6 trignometric functions,namely sin a cos a tan a cosec a sec a cot a where a is the angle. Trigonometric functions didn't exist without angles.
Trigonometric identities involve certain functions of one or more angles. These identities are useful whenever expressions involving trigonometric functions need to be simplified.
The sine and cosine are both trigonometric functions. Trigonometric calculations are used in many branches of engineering.
