Cosecant of input angle in radians
Y = csc(X)
Plot the cosecant function over the domain and as shown.
x1 = -pi+0.01:0.01:-0.01; x2 = 0.01:0.01:pi-0.01; plot(x1,csc(x1),x2,csc(x2)), grid on
Calculate the cosecant of the complex angles in vector
x = [-i pi+i*pi/2 -1+i*4]; y = csc(x)
y = 1×3 complex 0.0000 + 0.8509i 0.0000 + 0.4345i -0.0308 - 0.0198i
X— Input angle in radians
Input angle in radians, specified as a scalar, vector, matrix, or multidimensional array.
Complex Number Support: Yes
Y— Cosecant of input angle
Cosecant of input angle, returned as a real-valued or complex-valued scalar, vector, matrix or multidimensional array.
The cosecant of an angle, α, defined with reference to a right angled triangle is
The cosecant of a complex argument, α, is
In floating-point arithmetic,
csc is a bounded function. That
csc does not return values of
-Inf at points of divergence that are multiples of
pi, but a large magnitude number instead. This stems from the
inaccuracy of the floating-point representation of π.
