Cosecant in mathematics, the reciprocal of the sine function, or various organizational abbreviations like Computer Science Corporation.
In mathematics, from co- (complementary) and secant, literally meaning 'complementary secant.' The trigonometric term was established in the development of analytical trigonometry in the 17th-18th centuries.
The cosecant function is undefined whenever sine equals zero, creating vertical asymptotes on its graph - making it one of the more dramatic-looking trigonometric functions with its distinctive separated curves.
