Python cmath - sin() Function
The Python cmath.sin() function returns complex sine of a complex number z. It is a function on complex plane, and has no branch cuts. Mathematically, it can be expressed as:
Syntax
cmath.sin(z)
Parameters
z |
Required. Specify the complex number, representing an angle expressed in radians. |
Return Value
Returns the complex sine of z.
Example:
In the example below, sin() function is used to find out the complex sine of the given number.
import cmath
z1 = 2 + 2j
z2 = 2
z3 = 2j
print("cmath.sin(z1):", cmath.sin(z1))
print("cmath.sin(z2):", cmath.sin(z2))
print("cmath.sin(z3):", cmath.sin(z3))
The output of the above code will be:
cmath.sin(z1): (3.4209548611170133-1.5093064853236158j) cmath.sin(z2): (0.9092974268256817-0j) cmath.sin(z3): 3.626860407847019j
