Question

Given that Cos60=sin30=1/2 and cos30=sin60=root3/2.Evaluate tan60-1/1-tan30​

Answer 1

Answer:

root(3)

Step-by-step explanation:

assuming there are parentheses. (tan60-1)/(1-tan30​)

tan 60 = sin 60 / cos 60 = root(3)

tan 30 = sin 30 / cos 30 = root(3)/3

answer = (root(3) - 1)/(1- root(3)/3)

simplify/ rationalize denominator, root(3)

There's a more "simple" way to get the answer, but this solution is the most straightforward.
