I am not sure how to work solve this problem.
Find the value of cot ^-1(-1dividedby2)
Tutors, please sign in to answer this question.
Cot -1( -1/2) = tan -1 ( -2) = - 63 .43° = 296.57° / The way you wrote that is what it reads . Arc whose
or 180° - 63.43 Cot is -1/2 . Why don't you place (/) for divided by 2. Maybe it is Cot-1( -1) /2 ,then
Cot -1 ( -1) / 2 = - π/4 * 1/2 =- π/8 , or 3π/4
If the problem is [cot(x)]-1, then the answer is tan(x). You can get this from any table of trigonometric identities.
If the problem is [cot(x)](-1/2) then the answer is
