Explanation:
By evaluate I am assuming you mean give the
color(blue)" exact value" Obviously from a calculator the
tan(pi/3)≈1.732
But to obtain the exact value we can use the followingcolor(blue)" Exact value triangle" From this triangle we can obtain the exact values for sin/cos/tan of the angles
pi/3" and "pi/6 . These are very useful and appear on many occasions so worth memorising for future use.
From triangle we obtain.
tan(pi/3)=sqrt3/1=sqrt3 For the same angle :
sin(pi/3)=sqrt3/2 , cos(pi/3)=1/2
