nerdamer.csc(x: ExpressionInput): Expression
Computes the cosecant of an expression: csc(x) = 1/sin(x).
Returns exact values at well-known angles by inverting the result of sin.
throwscore!UndefinedError If x is ±∞ or an integer multiple of π (where sin(x) = 0).
Examples
csc('pi/2').text() // "1"
csc('pi/6').text() // "2"
csc('pi/4').text() // "sqrt(2)"
// Symbolic
csc('x').text() // "csc(x)"
