Find the Value Using the Unit Circle tan(pi/3)
Problem
Solution
Identify the coordinates on the unit circle for the angle
θ=π/3 Recall that for any angle
θ the coordinates(x,y) are(cos(θ),sin(θ)) Determine the values from the unit circle:
cos(π/3)=1/2 andsin(π/3)=√(,3)/2 Apply the formula for the tangent function, which is
tan(θ)=sin(θ)/cos(θ) Substitute the values into the formula:
tan(π/3)=√(,3)/2/1/2 Simplify the fraction by multiplying by the reciprocal of the denominator.
