Best ResponseYou've already chosen the best response.0But, I don't understand this:tan (alpha) = tan alpha

Best ResponseYou've already chosen the best response.1if alpha is in 1st quadrant  alpha is in 4th quadrant. In 4th quadrant, tan ratio is negative. hence, tan(x)=tan x

Best ResponseYou've already chosen the best response.0so (tan (x) is from the 4th quadrant and tan x in the first, how can it be negative in the first.

Best ResponseYou've already chosen the best response.1a ratio can't be in any quadrant.... x is an angle, its in 1st quadrant., then tan x is positive. if x is in 1st quadrant, x is in 4th quadrant, where tan x is negative, so, we need to bring out *minus* sign and write tan(x) =  tan x (....and NOT tan(x)=tan x)
