do you use any tricks for memorizing what sides are associated with sin, cos, tan?  Like soh cah toa

jim_thompson5910 · Answer

that's with respect to angle B

anonymous · Answer

the trick for memorizing the sides for sin, cos and tan are like so:

anonymous · Answer

SOH CAH TOA

anonymous · Answer

opp/hyp
adj/hyp
opp/adj :D

anonymous · Answer

so D would be our answer huh?

jim_thompson5910 · Answer

soh = sine opposite hypotenuse

cah = cosine adjacent hypotenuse

toa = tangent opposite adjacent

anonymous · Answer

no, the answer is b/a

anonymous · Answer

sin (b) points to b, which is its opposite, and the hyp is where the right angle points to.

jim_thompson5910 · Answer

sin = opposite/hypotenuse

cosine = adjacent/hypotenuse

tangent = opposite/adjacent

anonymous · Answer

you have to pretend you are an ant at the corner of B, THEN use the tricks people have been saying to pick the appropriate sides
