# tan() math function in python by R4R Team

- tan() is python math function which determine the tangent value of number.

Syntax-

math.tan(x)

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

Example-

tan(0) will return 0.0
tan(45) will 1.6197751905438615

program-

import math

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

output-

tan(90) : -1.995200412208242
tan(0) : 0.0
tan(45) : 1.6197751905438615
tan(60) : 0.320040389379563
tan(10) : 0.6483608274590866

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

program-

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

output-

tan(90) : 1.633123935319537e+16
tan(0) : 0.0
tan(45) : 0.9999999999999999
tan(60) : 1.7320508075688767
tan(10) : 0.17632698070846498
