Today Andrew and I began discussing basic trig functions. We used the acronym SOHCAHTOA to learn that sine=opp/hyp, cosine=adj/hyp, and tangent=opp./adj. We used the white board to draw a triangle and label the sides as opposite, adjacent, and hypotenuse. Then from the angle theta, we recognized what the sine, cosine, and tangent of theta would be. Then I have Andrew a problem on his own to try. With help, he was able to find the ratios for sine, cosine, and tangent.
