# sin() math function in python by R4R Team

- sin() is python math function which determine the sine value of number.

Syntax-

math.sin(x)

- Here x should be a numeric value.
- it return the sine value of x in radians.

Example-

sin(90) will return 0.8939966636005579
sin(0) will 0

program-

import math

print("sin(90) : ",math.sin(90))
print("sin(0) : ",math.sin(0))
print("sin(45) : ",math.sin(45))
print("sin(60) : ",math.sin(60))
print("sin(10) : ",math.sin(10))

output-

sin(90) : 0.8939966636005579
sin(45) : 0.0
sin(0) : 0.8509035245341184
sin(30) : -0.3048106211022167
sin(10) : -0.5440211108893698

-If we want to print the sine value of x, consider x should be in degree then

program-

import math

#these value are in degree
n=math.pi/180
print("sin(90) : ",math.sin(90*n))
print("sin(0) : ",math.sin(0*n))
print("sin(45) : ",math.sin(45*n))
print("sin(30) : ",math.sin(30*n))
print("sin(60) : ,",math.sin(60*n))
print("sin(10) : ,",math.sin(10*n))

output-

sin(90) : 1.0
sin(0) : 0.0
sin(45) : 0.7071067811865476
sin(30) : 0.49999999999999994
sin(60) : , 0.8660254037844386
sin(10) : , 0.17364817766693033
