Question

Find the approximate value of cot θ​, given that csc θequals=3.5891420 and θ is in quadrant I.

Answer 1

cot = 1/tan = cos/sin
csc = 1/sin
so
cot = csc*cos

cos = sqrt(1-sin^2)

cot = 3.589142*sqrt(1-1/3.589142^2)
=3.447019
or
3.45

Answer 2

thank you!

Answer 3

csc^2 θ = 1+cot^2 θ

so, ...
