Answer:

We have, csc257o−tan233osec254o−cot236o+2sin238o.sec252o−sin245o.

=csc2(90o−33o)−tan233osec2(90o−36o)−cot236o+2sin238o.sec2(90o−38o)−sin245o

=sec233o−tan233ocsc236o−cot236o+2sin238o.csc2

Step-by-step explanation:

We have, csc257o−tan233osec254o−cot236o+2sin238o.sec252o−sin245o.

=csc2(90o−33o)−tan233osec2(90o−36o)−cot236o+2sin238o.sec2(90o−38o)−sin245o

=sec233o−tan233ocsc236o−cot236o+2sin238o.csc2
