Answer 1

Answer:

HOPE THIS HELPS YOU. THANK U

Answer 2

Integration

∫ cosec²x log ( sec x ) dx

use Integration by parts

take log ( secx ) as a first function

then ,

log (sec x )× ∫ cosec²x - ∫( 1/ secx )× sec x tan x × -cot x dx

= log (sec x ) × (- cot x ) + ∫ tan x × cot x dx

= log (sec x ) × (- cot x ) + x + c
