especially the radians?

Draw Circle with radius. If you are familiar with 30-60-90 and 45-45-90 triangle, just use that for remembering the unit circle

iknow the degree measurements..i have a quiz tomorrow and have to fill out the blank circle with cos, sin and radians. I just need tricks to remember how to fill it out

do you just need 90, 180, 370, 0 degrees, or all reference anglew
anonymous
  • anonymous
all reference angles

you only need to know three angle 30,45,60 for every else you can derive easily

If you know the values for 30,60,45 they will workfor all the angles, the signs will change depending what quadrant the angle is in

ok i got that what about the radians for each angle how do you remember those
anonymous
  • anonymous
remember that one radian is 180 degree. So always know what's the ratio between the angle and 180 and then stick radian. So If i were to find radian eqivilent of 90, I would find ration 90/180=1/2 stick radian sign 1/2 radian

so then 60/180 = pi/3
anonymous
  • anonymous
radian/3
anonymous
  • anonymous
pi/3 radian

what about tangent
anonymous
  • anonymous
iknow it is sin/cos but i cant divide radicals by radicals
anonymous

So for example lets find tangent of 30 sin 30= 1/2 cos 30= sqrt(3)/2 1/2* 2/sqrt(3) 2/2sqrt(3)
