Question

In which quadrant does 0 lie if the following statements are true: cos 0<0 and sin 0<0

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

cos θ < 0

sin θ < 0

Step 02:

trigonometry:

we must analyze the graph to find the solution.

cos θ < 0 ===> -

sin θ < 0 ===> -

quadrant III

The answer is:

quadrant III
