Just apply R-angle formula... textbook has the formula and enough examples?
Our teacher didn't show us for fraction and we don't use the tb often but will try
Just use R-angle for the denominator... then substitute the result into the fraction... then analyse or reason out how the fraction affects the min / max.
Noted thankss
