Tangent of argument in radians
Y = tan(X)
Plot the tangent function over the domain .
x = (-pi/2)+0.01:0.01:(pi/2)-0.01; plot(x,tan(x)), grid on
Calculate the tangent of the complex angles in vector
x = [-i pi+i*pi/2 -1+i*4]; y = tan(x)
y = 1×3 complex 0.0000 - 0.7616i -0.0000 + 0.9172i -0.0006 + 1.0003i
X— Input angle in radians
Input angle in radians, specified as a scalar, vector, matrix, or multidimensional array.
Complex Number Support: Yes
Y— Tangent of input angle
Tangent of input angle, returned as a real-valued or complex-valued scalar, vector, matrix or multidimensional array.
The tangent of an angle, α, defined with reference to a right angled triangle is
The tangent of a complex argument, α, is
In floating-point arithmetic,
tan is a bounded function. That
tan 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.
