Question

Solve for theta. Find all solutions. Please show work.

Answer 1

cot (theta) = sqrt(3)/3

Answer 2

is that cot suppose to cos?

Answer 3

cos-1(sqrt(3)/3)
54.7 degrees

Answer 4

cot = 1/tan
cot = cos x / sin x etc.

Answer 5

no, its supp to be cot

Answer 6

I posted the same question on yahoo:


sin(theta)=1/2

I know sin of 1/2 is pi/6

To find the other one you need to find the opposites that are both the same, you need to find positive opposites, quadrant 1 and 2 opposites are both positive. 180-30=150 and 150/30=5 so 5pi/6

pi/6+2pi (n), 5pi/6+2pi (n)

Using that logic, I know how to find sin and cos but it wont work with tan,cot,csc and sec.

So my question is, how would I find:

csc(theta)=-1/1

cot(theta)=(sqrt)3)/3

sec(theta)=-(sqrt)2)

tan(theta)=undefined


Is were im stuck on

Answer 7

oh i haven't learned csc and sec yet. im sorry

Answer 8

Evaluate sqrt(3)/3 =0.577 and look up cot @ values, finding @ that way to start. Well, I hit on it as @=30o lucky guess. where else would
cot @ = x/y = 0.577?
