Best ResponseYou've already chosen the best response.1Thank you, for the help, however, I am still trying to solve it... the goal is to show the steps how the left side will equal the right side. I decided to convert tan to cos/sin and got stuck. Attempted to use tan and cot and got even more stuck. I am interested to see what I am doing wrong... Here is a PDF of what I attempted.. and the equation... I need to verify... [(tanx+tany)/(\cot x+\cot y) = (\tan x \tan y1) / (1 \cot x \cot y\]
