HEYA GUYS..did anyone explain me 9 class maths chapter trignometry.....plz explain clearly by using any page of urs

Answer»

Hey _____
its very easy ,firstly just learn all the identities ,and the trignometry table
and just try to see what the question is SAYING and what to FIND or what to prove

All the QUESTIONS are SOLVED by using identities and formulas

as taking a very simple example
sin {}^{2} + cos {}^{2} = 1 \\ sin {}^{2} +1 - sin {}^{2} = 1 \\ 1 = 1 \\ lhs = rhs
in this we use an identity
thanq
