Question

find the value of cot(11pi/6)

Answer 1

the exact value or just value

Answer 2

my paper only says value so thats what im going off of

Answer 3

remember that 11pi/6 is in 4th quadrant,
so only cos and sec ratio will be positive...
cot(11pi/6)=-cot (2pi-11pi/6)---->as cot x=-cot(-x)=-cot (2pi-x)
=-cot(pi/6)=- sqrt(3)
now cos(11pi/6)=cos (2pi-11pi/6)---->as cos x=cos(-x)=cos (2pi-x)
=cos(pi/6)=sqrt(3)/2
csc(11pi/6)=-csc (2pi-11pi/6)---->as csc x=-csc(-x)=-csc (2pi-x)
=-csc(pi/6)=- 2

Answer 4

i know the answer is the sqrt of 3 i just dont get were the -cos and the 2 comes from

Answer 5

Well is this for Geometry.

Answer 6

advance function and modeling

Answer 7

Oh then sorry thats alittle more advanced than i have gone with math.

Answer 8

ok well thanks anyways

Answer 9

Yah Im only in Geometry and the highest math ive worked with is precal and that was for an engineering class.
