Question

cot(11pi/12)

Answer 1

1/tan(11(180)/12) = 1/tan(11*15) = 1/tan(165) = 1/(sqrt(3) - 2) = -(sqrt(3) + 2) = -3.73

Answer 2

can you explain the answer a little simpler. i'm still confused

Answer 3

pi = 180 degrees

Answer 4

also tan(165) = (tan (30) + tan (135))

Answer 5

okay, another question. where did you get the sqrt after 1/tan(165)?

Answer 6

cot(x) = 1/tan(x)

Answer 7

thanks
