Question

(sin0+ sec 0) + (cos 0 + cosec ) = (1 + cosec 0 sec 0).​

Answer 1

Step-by-step explanation:

( sin0 + sec0 ) +( cos 0 + cosec0)

( 1/cosec0 + sec0 ) +( 1/sec + cosec0)

(sec/cosec ) + ( cosec/sec) ( 1/sin =cosec 1/cos=sec)

( sin /cos ) + ( cos / sin)

sin / cos + cos/ sin

sin^2 + cos^2/ sin cos ( sin^2 +cos^2 =1)

1/ sin cos

cosec ×cos
