Em is that the cot and tan graph meet at where pi/4? or 45 degree?
yeah easy way to do this is to switch it into cot = cos/sin tan = sin/cos
so yeah pi/4
here is a really easy trick to memorize the cos & sin simple angles http://www.youtube.com/watch?v=1-hrT1Ys390
in combination with http://www.youtube.com/watch?v=ao4EJzNWmK8 reaaaaally easy to get them all down
can't find the one i was looking for for the second one but that one will suffice patrickjmt is a beast
oh patrick, i love his vids too
yeah definitely :) check out the first video for sure though it's extremely helpful when you are learning you still have to memorize the first quadrant but you really need to have them down anyway, along with pi/2, pi, 3pi/2 and 2pi
the rest of the radians/degrees you can figure out the exact value using the above method
anyway good luck to you :0
