Answer 1

Step-by-step explanation:

X Given : tan & + Sine = m tan o -Sino = n m2- n2-umm Find : Proue that Solution: Add tan o tsind = m and tand-Sind =n then. Mi n = a tan O Simplify the tan 0 + Sind them, =m and tand - sind -n Sub shilut m -n - aSino m2 n?: (min) Cm-n) Now, = > m?- n? =ų sino tand = dan O 1 sino )C tcuno - Sin ) - tanb - sin?g = 4 Vtan 20 -sin?0 mn NOw , 4imn = 4/ Eino -sin?0 4 mn = 4 Sin O tan o equating O cand O , ue howe, m2- n2 4J mn. (o) (m? -n?) 16 mn. Hence Provod .
