Question

14. If cos A =1/2
and sin B
=1/√2
, find the
value of
$\frac{tan \: A \: - tan \: B \: }{1 + tan \: A \times tan \: B}$
Here angles A

and B are from the same triangle.
​

Answer 1

applying formulae but 'a' and 'b' can't be in same triangle as they are exceeding 90° but they can be in same triangle if third angle is not 90°
