Using the unit circle, it is found that the approximated value is cot(λ) = -0.383.
What is the unit circle?
For an angle [tex]\theta[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\theta}, \sin{\theta})[/tex].
Hence, the point means that we have that cos(λ) = -0.358, sin(λ) = 0.934. The cotangent is given by cosine divided by sine, hence:
cot(λ) = -0.358/0.934 = -0.383.
