32.1.1. Understanding Trigonometric Functions
import math
print("degrees 0 30 45 60 90")
#convert the given degrees to radians
a=0
b=math.radians(30)
c=math.radians(45)
d=math.radians(60)
e=math.radians(90)
#print the trigoometric values of the radians for sin, cos, tan
print("sin",math.sin(a), math.sin(b), math.sin(c), math.sin(d), math.sin(e))
print("cos",math.cos(a),math.cos(b),math.cos(c),math.cos(d),math.cos(e))
print("tan",math.tan(a),math.tan(b),math.tan(c),math.tan(d),math.tan(e))
32.2.1. Understanding Mathematical Constants
(c) math.tau is equal to 2π.
(e) math.nan stands for "Not a Number".
(f) math.pi is an irrational number.
32.2.2. Program to print values of mathematical constants
#import math module
import math
print("constant\tvalue\tdata type")
#print value and type of pi
print("pi\t",math.pi,"\t",type(math.pi))
#print value and type of e
print("e\t",math.e, "\t",type(math.e))
#print value and type of inf
print("inf\t", "{:17}".format(math.inf), "\t", type(math.inf))
#print value and type of nan
print("NaN\t", "{:17}".format(math.nan), "\t", type(math.nan))
