If tan y is positive and sin y is negative, in which quadrant would y lie?
Answer Details
The value of y can only lie in the third quadrant.
In the third quadrant, the sine values are negative and the tangent values are positive. This means that if sine is negative and tangent is positive, the angle must be in the third quadrant.
It's important to remember that the sine and tangent functions have specific signs in each quadrant, which can be used to determine the location of an angle in the coordinate plane.
