Question

please help
true or false and explain
csc^-1[csc(-pi/4)]=-pi/4

sec[sec^-1(sqrt30]=sqrt3

Answer 1

true for both.

Answer 2

think of this. if you have pi/4 dollars in your pocket, I give you some (csc) and then I take that some (csc^-1) so, you have nothing add or subtract. that means you have what you had before. (pi/4)

Answer 3

thank you so much.
