Question

What is the value of [ cosec (75° + x) - sec(15° -x) - tan(55°+x ) + cot(35° - x)] ?

Answer 1

Answer:

Step-by-step explanation:

cosec (75° + x) - sec(15° -x) - tan(55°+x ) + cot(35° - x)

cosec (75° + x) - sec(90°-(75°+x)) - tan(55°+x ) + cot(90°-(55° + x))

cosec (75° + x) -  cosec (75° + x) -  tan(55°+x ) + tan(55°+x )

=0
