    I'm doing identities in math. What does sine, cosine, tangent, cosecant, secant, and cotangent equal?

            tan=sin/cos
            cot=cos/sin
            sin=1/csc
            csc=1/sin
            cos=1/sec
            sec=1/cos
            tan=1/cot
            cot=1/tan
            sin^2+cos^2=1
            and theres a few more

              We did these this year and it has dropped me from a solid b to a low c

                    Sin is Opposite divided by Hypotinus(spelling) ( the longest side)

                    COS is Adjacent divded by Hyp.

                    TAN is Opposite divided by Adjacent

                    you set it up in calculator like: (press) TAN ..put in the degree angle and do the same for us..COS(Angle degree), TAN (degree angle)

                    with that #, you do: (answer you got from the calculator) divided by 1, set that equal to the thing i put above (Opposite/Hyp or w.e your using). .. cross multiply and you got the answer

                    Secant is a line going through circle..tangent is where a line meets the end of circle



                    damn thats going back awhile. thats all i got. hope its good

                        You learn the trig functions long before calc, like in geometry.

                        That is correct comahan

                          Yep, I think I learned them in 8th grade. Although we go over them basically every year. Maybe csc, sec, and cot were in 10th.

                            I was expecting an Office thread. I'm disappointed.

                              im in 9th (geometry) and learned about half that, math isnt my best subject though, but the sin, cosine, and tan parts were pretty easy.
