The sine, cosine, and tangent ratios each have a reciprocal ratio. The reciprocal ratios are cosecant (csc), secant (sec), and cotangent (cot). use triangle ABC to write the definitions
sec A
csc B
cot B

Best ResponseYou've already chosen the best response.0Are you given or have you learned that csc= reciprocal of which , and sec of which , and cot is reciprocal of which?

Best ResponseYou've already chosen the best response.0csc= sin inverse. cot= tan inverse, sec= cos inverse. (Sorry for the informal uses of words)

Best ResponseYou've already chosen the best response.0So the normal numerator of sin would be denomenator of csc , and etc..

Best ResponseYou've already chosen the best response.1For the sake of clarity, let's not use "inverse" in this manner. This is a reciprocal. I can see why you used "inverse", but a few lessons down the road, you WILL regret it if you call it that. Pick an Angle!! Let's call it "B". It your drawing, it's one of the acute angles. After that, the definitions require memorization. You will be required to know which side is adjacent to the given acute angle and which side is opposite the given acute angle. \(\sin(B) = \dfrac{m(Opposite\;Side)}{m(Hypotenuse)} = \dfrac{1}{\csc(B)}\) \(\cos(B) = \dfrac{m(Adjacent\;Side)}{m(Hypotenuse)} = \dfrac{1}{\sec(B)}\) \(\tan(B) = \dfrac{m(Opposite\;Side)}{m(Adjacent\;Side)} = \dfrac{1}{\cot(B)}\)

Best ResponseYou've already chosen the best response.1SecA = 1/cosA Find cosA first, this will let you find sec A. CosA = adjacent/hypotenuse. dw:1376263854146:dw

Best ResponseYou've already chosen the best response.1Correct! Now try cscB = 1/sinB Sin = opp/hyp. dw:1376264245185:dw

Best ResponseYou've already chosen the best response.1Correct. Now try cotB. cotB = 1/tanB.

Best ResponseYou've already chosen the best response.0@agent0smith do i have to simplify ^^

Best ResponseYou've already chosen the best response.0so the cot (b)= 4/3 csc (B)=5/3 sec (B)=5/3
