Since cot x = cos x / sin x, if cot x = 1/2, with the angle x in the first quadrant,

then cos x = 1 and sin x = 2

(1) State true or false. Is this a possible situation?

(2) If false, explain why.

no way!

sinx x has to be a value between -1 and +1, can't be 2

since cot x = 1/2 ---> opposite = 2, adjacent = 1

construct a triangle with sides 1 and 2, the hypotenuse then is √5

cosx = 1/√5

sinx = 2/√5
