Python | math.sin() function
In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.sin()
function returns the sine of value passed as argument. The value passed in this function should be in radians.
Syntax: math.sin(x)
Parameter:
x : value to be passed to sin()
Returns: Returns the sine of value passed as argument
Code #1:
import math
a = math.pi / 6
print ( "The value of sine of pi / 6 is : " , end = "")
print (math.sin(a))
|
Output:
The value of sine of pi/6 is : 0.49999999999999994
Code #2:
import math
import matplotlib.pyplot as plt
in_array = [ - 3.14159265 , - 2.57039399 , - 0.28559933 ,
0.28559933 , 2.57039399 , 3.14159265 ]
out_array = []
for i in range ( len (in_array)):
out_array.append(math.sin(in_array[i]))
i + = 1
print ( "in_array : " , in_array)
print ( "\nout_array : " , out_array)
plt.plot(in_array, out_array, color = 'red' , marker = "o" )
plt.title( "math.sin()" )
plt.xlabel( "X" )
plt.ylabel( "Y" )
plt.show()
|
Output:
in_array : [-3.14159265, -2.57039399, -0.28559933, 0.28559933, 2.57039399, 3.14159265]
out_array : [-3.5897930298416118e-09, -0.5406408168673427, -0.2817325547837714, 0.2817325547837714, 0.5406408168673427, 3.5897930298416118e-09]
