Math, microeconomics or criminal justice
tan(0) = 0 not 1
but 0 probably means theta, IF so, then tan(theta) = 1 means theta = pi/4 or 5pi/4 + 2npi for n=any integer
sin(theta) means sin(pi/4) or sin(5pi/4) = sqr2/2 or -sqr2/2 = about 0.707 or - 0.707
theta = pi/4 or 45 degrees or 5pi/4 or 225 degrees.
