Explanation:
Six trigonometric functions are ratio of sides with their angle in right angled triangle.
Six trigonometric functions are:
Sinθ = Perpendicular / Hypotenuse
Cosθ = Base / Hypotenuse
Tanθ = Perpendicular / Base
Cotθ = Base / Perpendicular
Secθ = Hypotenuse / Base
Cosecθ = Hypotenuse / Perpendicular
