Question

If the angles of ΔABC are in ratio 1:1:2, respectively (the largest angle being angle C), then the value of secA cosec B – tanA cot B is

Answer 1

Make a triangle ABC with angle C=90

Consider secA/cosecB

This will be equal to AB/AC x AC/AB=1

Consider tanA/cotB

This will be equal to BC/AC x AC/BC=1

Hence, 1-1=0
