prove the following:

Answer 1

HEY FRIEND

HERE IS YOUR ANSWER.

TO PROVE :

3cos²π/4+sec2π/3+5tan²π/3=29/2

PROOF :

LHS:

=3cos²π/4+sec2π/3+5tan²π/3

=3(1/√2)²+sec(π-π/3)+5(√3)²

[USING sec(π-@)= -sec@]

=3(1/2)+sec(-π/3)+5×3

=(3/2)-2+15

=3/2+13

TAKING LCM

=(3+26)/2

=29/2

=RHS

HOPE THIS HELPS YOU
