Cotangent of angle in radians
Plot the cotangent function over the domain and .
x1 = -pi+0.01:0.01:-0.01; x2 = 0.01:0.01:pi-0.01; plot(x1,cot(x1),x2,cot(x2)), grid on
Calculate the cotangent of the complex angles in vector
x = [-i pi+i*pi/2 -1+i*4]; y = cot(x)
y = 1×3 complex 0.0000 + 1.3130i -0.0000 - 1.0903i -0.0006 - 0.9997i
X— Input angle in radians
Input angle in radians, specified as a scalar, vector, matrix, or multidimensional array.
Complex Number Support: Yes
Y— Cotangent of input angle
Cotangent of input angle, returned as a real-valued or complex-valued scalar, vector, matrix or multidimensional array.
The cotangent of an angle, α, defined with reference to a right angled triangle is
The cotangent of a complex argument α is
In floating-point arithmetic,
cot is a bounded function. That
cot 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.
