Assalamoalaikum!!

remember for such equations,i.e. if the eqn contains tanx along with sinx or cos x then u have to first write sinx/cosx
then u solve..i'm sure if u do this u'll get it...and yeah remember sin^2 x = 1 - cos^2 x

these two things if u know and solving using a quadratic eqn. u can do it urself!

try doing it...if u have any problems..i'll help u do it InshAllah!
