Trigonometric Ratio: Cosecant
How to solve cosecant (trigonometric ratio) problems: definition, example, and its solution.
Cosecant is the reciprocal of sine.
[sin A = (Opposite side) / (Hypotenuse)]
So csc A = (Hypotenuse) / (Opposite side).
csc A = (hypotenuse) / (opposite side)
In the given right triangle,
the opposite side is missing.
So find the opposite side
by using the Pythagorean theorem.
(opposite side) = √7
csc A = 1 / sin A
So sin A = √7/4.
So, its reciprocal, cosecant is
csc A = 4/√7.
