Question

prove that :

sin a( 1 + tan a ) + cos a ( 1 + cot a ) = sec a + cosec a​

Answer 1

Answer:

hope this answer helps

Answer 2

Step-by-step explanation:

considering LHS = sina(1+tana) + cosa (1 + cota )

= sina ( 1 + sina / cosa) + cosa ( 1 + cosa / sin a)

= sina ( cos a + sina / cos a) + cosa ( sina + cosa / sin a )

= sin2 a + sin a . cos a / cos a + cos2a + sina . cos a / sin a

= pls solve half

sry i cant solve further
