nUse the definitions of the trigonometric ratios for a right triangle to derive a cofunction identity for tan(90° - A). Show your steps.

Question

jdoe0001 · Answer

would you say that tangent = sine/cosine?    check your trig identities

huh

jdoe0001 · Answer

do you have a trigonometry sheet with basic trigonometric identities?

anonymous · Answer

no

hmm, do you have a Unit Circle?

lol no

Alright so in a right angle triangle, one angle is 90, so the other two would sum up to another 90. If you can rearrange the equation, and apply trigonometry to it, you should get it. It would help to sketch and lable too.
