csc, csch
2csc, csch
Purpose Cosecant and hyperbolic cosecant
Syntax Y = csc(x)
Y = csch(x)
Description The csc and csch functions operate element-wise on arrays. The functions’
domains and ranges include complex values. All angles are in radians.
2-348
Y = csc(x) returns the cosecant for each element of x.
Y = csch(x) returns the hyperbolic cosecant for each element of x.
Examples Graph the cosecant and hyperbolic cosecant over the domains – π < x < 0 and
0 < x < π .
