Question

What is cosec(75°+ theta)- sec(15°- theta)=?

Answer 1

Answer:

Step-by-step explanation:

Cosec (75-theta)-Sec (15-theta)=?

we know that cosec(90-theta)=sec(90-theta)

so cosec((90-(15-theta)))-sec(15-theta)

hence we will get sec(15-theta)-sec(15-theta) as cosec(90-theta)=sec(90-theta)

ANSWER=sec(15-theta)-sec(15-theta)=I guess you know subtraction

=0
