Question

Generally, How do I prove a reciprocal identity?

Answer 1

yeah, they're definitions

Answer 2

so like, cd(theta) = 1/ sin theta, kind of thing?

Answer 3

they are defined that way??
sin = p/h, and csc = h/p

LOL posted some other link

Answer 4

not cd, csc

Answer 5

Ok. Thank you guys

Answer 6

\(\LARGE sin\theta = \frac{p}{h} = \frac{1}{h/p} = \frac{1}{csc \theta}\)

Answer 7

though you can hardly say it is a proof ... rather seems as definitions.
