given tanθ = √5, find secθ and cotθ in quadrant III
----
Note: x and y are both negative in QIII
-----
By definition, tan = y/x
------
So, y = -sqrt(5) and x = -1
------
Then, r = sqrt[(sqrt(5))^2+(1)^2] = sqrt[5+1] = sqrt(6)
-----
Ans: sec(t) = r/x = -sqrt(6) and cot(t) = x/y = 1/sqrt(5) = (1/5)sqrt(5)
----------
Cheers,
