from math import sin, cos, pi # This file demonstrates the usage of radians vs degrees in computational tools. # Say we wish to compute the numerical value of cos(30 degrees) result1 = cos(30) print "cos(30) = " + str(result1) # You also may recall that 30 degrees is equivalent to pi/6 radians. result2 = cos(pi/6) print "cos(pi/6) = " + str(result2) # Click the "Run" button above, and see the results which print out below. # - Why are these different? # - Which one is correct? #result3 = cos(30*(???)) #print "result3 = " + str(result3)
