Python – cmath.asin() function

cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.asin() function returns the arc sine value of a complex number. The value passed in this function can be int, float, and complex numbers.

Syntax: cmath.asin(x)

Parameter:This method accepts only single parameters.

• x :This parameter is the value to be passed to asin()

Returns:This function returns the arc sine value of a  complex number.

Below examples illustrate the use of above function:

Example #1 : In this example we can see that by using cmath.asin() method, we are able to get the values of arc sine by passing any value to it.

Python3

# Python code to implement
# the asin()function

# importing "cmath"
# for mathematical operations
import cmath

# using cmath.asin() method
val = cmath.asin(3)

print(val)

Output:

(1.5707963267948966+1.762747174039086j)

Example 2:

Python3

# Python code to implement
# the asin()function

# importing "cmath"
# for mathematical operations
import cmath

# using cmath.asin() method
val = cmath.asin(2 + 5j)

print(val)

Output:

(0.374670804825527+2.3830308809003258j)
