in a triangle ABC, ANGLE A =45

(tan b)*(tan c) =k.......

then find a relationship in k....that is find out an equality satisfying a quad. exp. in k

hi rahul

apologies for delay but i was not able to get that you want a quadratic in k eliminating a , b and c and their trigonometric ratios

or quadratic in k with a , b , c or their trigonometric ratios pls specify
