Question

Cos a/ (sec a -tan a) = 1 + sin a

Answer 1

HOLA!!

HERE IS UR ANSWER::--

(sin o + cos o ) ( sec o+ cosec o)

=(sin o+ cos o) (1/ cos o + 1/ sin o)

= (sin o + cos o)(sin o+ cos o/sin o. cos o)

=(sin o+ cos o)^2/ sin o . cos o

=1+2sin o cos o/ sin o.cos o

=1/sin o. cos o+2 sin o cos o/ sin o cos o

=1/sin o . 1/cos o+2

=2+cosec o . sin o {PROVED}
