Question

How to calculate the tangent of an angle of N radians in Python

Answer 1

import math

print("math.tan(45 * math.pi / 180.0) = ", math.tan(45 * math.pi / 180.0))
print("math.tan(3 * math.pi / 4) = ", math.tan(3 * math.pi / 4))
print("math.tan(5 * math.pi / 4) = ", math.tan(5 * math.pi / 4))
print("math.tan(7 * math.pi / 4) = ", math.tan(7 * math.pi / 4))
print("math.tan(math.pi / 4) = ", math.tan(math.pi / 4))
print("math.tan(0.0) = ", math.tan(0.0))
print("math.tan(-0.0) = ", math.tan(-0.0))


'''
run:

math.tan(45 * math.pi / 180.0) =  0.9999999999999999
math.tan(3 * math.pi / 4) =  -1.0000000000000002
math.tan(5 * math.pi / 4) =  0.9999999999999997
math.tan(7 * math.pi / 4) =  -1.0000000000000004
math.tan(math.pi / 4) =  0.9999999999999999
math.tan(0.0) =  0.0
math.tan(-0.0) =  -0.0
