Question

plzzz koi solve krdo yaar net se ya kahi se bhi solution bhej do

Answer 1

put value of tan & solve it

Answer 2

5tan²Ѳ - 5tanѲ -1 = 0
5tan²Ѳ - 5tanѲ = 1
5tanѲ(tanѲ - 1) = 1
tanѲ- 1 = 1/5tanѲ
tanѲ - 1 = 1/5×1/tanѲ
tanѲ - 1 = cotѲ/5 (since 1/tanѲ = cotѲ)
5(tanѲ -1) = cotѲ
5tanѲ - 5 = cotѲ
5tanѲ - cotѲ = 5
