csc(-330°) can be expressed as a trigonometric function of an angle in Quadrant I as csc(30°)

What are trigonometric functions?

Trigonometric functions are specific functions of angles. There are six functions which are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Given csc(-330 degrees)

-330° = 360 - 330 = 30°

-330° is the same as 30° angle found in quadrant I. Hence:

csc(-330°) can be expressed as a trigonometric function of an angle in Quadrant I as csc(30°)
