Best ResponseYou've already chosen the best response.0memorizing them isn't incredibly difficult, I had to for precalculus. These look correct! I didn't find any mistakes in my quick glance. I'll continue looking though.

Best ResponseYou've already chosen the best response.1So basically each finger on the hand has a different angle. Thumb90 Index60 Middle45 Ring30 Thumb0 The palm is always 2. On top= cosine (side where the thumb points up) On bottom=sine (side where the pinky finger is) Say for example we are given the problem find Cos(pi/6) We know that pi/6 is a 30 degree angle, thus we put our ring finger down. We also can tell from the unit circle that when cos is pi/6, cos is positive. We put our ring finger down and then see that we have up on the cosine side above the folded finger. We have 3 fingers (ON TOPCOSINE) Now, anytime we look at the fingers, we need to square root them. So we say sqrt of 3, and then we put the value above the 2 in the palm bc this isn't Tangent or Cotangent where we have to look at both Sine and Cosine. Therefore, the answer for cos(pi/6) is sqrt3/2. Make sense? :)

Best ResponseYou've already chosen the best response.1I would hope so! Are they all correct? The quiz tomorrow is timed and I have a lot of other tests/discussions, and work in school tomorrow. I hope I'm not worn out by the time I get to this quiz! :) .

Best ResponseYou've already chosen the best response.0tan 120 is it sqrt{3} or positive ?

Best ResponseYou've already chosen the best response.0It's negative, because its in the second quadrant.

Best ResponseYou've already chosen the best response.0http://prntscr.com/8at9tn looks like square root tan isn't positive in 2nd q

Best ResponseYou've already chosen the best response.0no i mean on the worksheet :) there is just sqrt{3}

Best ResponseYou've already chosen the best response.0Tangents are negative in the second and fourth. Cosines are negative in the second and third. Sines are negative in the third and fourth.

Best ResponseYou've already chosen the best response.0So just being careful about which quadrant everything is in should help. Drawing the circle at the top of the test is what helped me.
