Question

Prove that (Tan 60°+1/Tan 60°-1)=(1+Cos 30°/1-Cos 30°)

Answer 1

Answer:

they are not equal

Step-by-step explanation:

(tan60° + 1)/(tan60°-1)  =  (√3+1)/(√3-1)  = (√3+1)²/3-1 = (4+2√3)/2 = (2+√3)

(1+cos30°)/(1-cos30°) = (1+ √3/2) / (1 - √3/2)

                                  =  (2+√3)/(2-√3)

                                  = (2+√3)²/4-3

                                  =  7 + 4√3
