Trignometric Ratios

Trignometric Ratios
These are used to compare the two sides,from the three that the triangle have.The side opposite to right angle is called hypotenuse(H),the side opposite to the known angle is said as perpendicular(P) and the third side is called base(B) and θ be an angle.

The comparison between hypotenuse and perpendicular is shown by two functions-
        sinθ=P/H
        cosecθ=H/P
The comparison between hypotenuse and base is shown by two functions-
        cosθ=B/H
        secθ=H/B
The comparison between perpendicular  and base is shown by two functions-
        tanθ=P/B
        cotθ=B/P
