HI!!

i guess you are supposed to figure you are in quadrant 1, otherwise you cannot know for certain what cosine or tangent is

  • laughoutloud
yes, that's all i have learned lol

  • misty1212
what you need is a good trig cheat sheet look below
misty1212
  • misty1212
sine is the second coordinate look at the unit circle on the last page of the cheat sheet find the point where the second coordinate is \(\frac{1}{2}\) the cosine is the first coordinate of that point

let me know when you see it

ok I found it so its, √3/2? which must mean that tan is 1/√3?
misty1212
  • misty1212
yes and yes

THANK YOU SO MUCH!!!!!

  • misty1212
although if you have answer choices, the tangent might be called \(\frac{\sqrt3}{3}\)

  • misty1212
same thing, just with the denominator rationalized
