if it's angle a then find the opposite side and the hypontnuse(opp the right angle) to find an angle, look at the sides, then see if it matches with sine, cosine or tangent. to find the sine of a triangle look at what angle is given to you. well to begin Sine= opposite/hypotnuse, Cosine= opposite/hpotenuse and tangent=opposite/adjacent. Ana Paula Tabalipa :I remember it using "some old hippy, caught another hippy, tripping on acid"Sine=opposite/hypot, cos=adjacent/hypo, tangent=oppotite/adjacent Lucinda Weist :yes, i just got through taking a test over it. You should be getting a good night sleep. Learning is a process that can't be achieved over night. over opposite) Rihanna :secant is the reprical of cosine Carissa Rosario :cotangent is the reciprical of tangent Veronica Hart :another way to remember it is Oh Heck Another Hour Of Algebra (O stands for opposite, H stands for hypotanuse, A for adjacent Kim Eternity :good luck !!! Michelle McClatchy :Next time don't wait till the last minute to study. OA means Opposite/Adjacent Mary Jo Randle :soh= sine (opposite over hypotenuse) Olympia Dukakis :cah= cosine (adject over hypotenuse) Vicky Palacios :toa= tangent (opposite over adjacent) Katherine Brooks :cossecant is the reciprical of sine (hyp. AH means Adjacent/Hypotenuse Nina Tapanin :T is tangent. The OH means Opposite/Hypotenuse Pady Basch :C is cosine. Bibiana Beglau :help! I have ACT 2morrow and I need a refresher on SOH-COA-TOA! anyone want to tell me what to do with what Gunilla Karlzen :SOH CAH TOA helps with right triangles.
