Question

Name the quadrant in which cotθ and cosθ are negative.

Answer 1

Recall "All Silver Tea Cups"
or All Sin Tan Cos

Quadrant 1 : All trigonometric ratios are positive.
Q2: only sin (and cosec)
Q3 : only Tan (and cot)
Q4 : only Cos (and cosec)

So, cot theta will be negative in Quadrant 2,4
and cos theta will be negative in Quadrant 2,3

In Quadrant 2, both will be negative!
