Today JPaul and I worked on signs of trig functions depending on which quadrant the terminal side lands in. First we recalled that sine goes with y, cosine goes with x, and tangent is y/x. JPaul asked why this is true, so we went back to previous notes, and I reviewed with him the proof involving the Pythagorean Theorem. Next, we practiced problems where the sign of a trig function was given and then it asked which possible quadrants the terminal side could land in. JPaul had to consider if the x or y values were positive/negative in those quadrants. JPaul understood the content, but was a little slower than usual with his responses. I asked him what time he went to bed last night and he said 10:04. (LOL on the specificity). Perhaps this was more challenging for him, so we will review again tomorrow to ensure he truly gets it before building on it.
