The equation y=csc(x) is a trigonometric function that looks like repeating regular and upside down "U"s. This function can also be written as y=1/sin(x) because cosecant is the inverse of the sine function.
The function has vertical asymptotes that repeat halfway through each period, which is 2(pi) units. Trigonometric functions are normally graphed on an x-axis and y-axis with radian units. The radian units can be converted to degrees, however, by substituting 180 for pi. So, pi/2 becomes 90 degrees, and 2(pi) becomes 360 degrees. There are five other trigonometric functions including y=sin(x), y=cos(x). y=tan(x), y=sec(x) and y=cot(x). Secant is the inverse of cosine and cotangent is the inverse of tangent.
