As we know from the Trigonometric functions
tanθ=yx
tan60=yx
3=yx
Now check the points whose yx value is equal to 3. Than we cansay that the point is on the terminal side of theta.
a) For the point (-1,-1)
b) For the point (1,3)
yx=31=3
c) For the point (3,1)
yx=13=13
So the point b is the terminal side of theta.
Result : B) (1,3)
