On a Unit Circle, the cosine is the x coordinate of the point on the circle represented by an angle. Angles greater than 90° (pi/2 radians) and less than 270° (3*pi/2 radians) are to the left of the y-axis, so x is negative.
Quadrant I is the upper right quadrant (x positive, y positive) 0° < ɵ < 90°
Quadrant II is the upper left quadrant (x negative, y positive) 90° < ɵ < 180°
Quadrant III is the lower left quadrant (x negative, y negative) 180° < ɵ < 270°
Quadrant IV is the lower right quadrant (x positive, y negative) 270° < ɵ < 360°

In which quadrant are both x and y negative?
The third (or SouthWest) quadrant.
Is tan theta in the 3rd quadrant negative?
In the third quadrant, both the x and y coordinates are negative. Since tangent is defined as the ratio of the opposite side to the adjacent side in a right triangle, in the third quadrant where both sides are negative, the tangent of an angle theta will be positive. Therefore, tan theta is not negative in the third quadrant.
What quadrant is negative 145?
Assuming the question is about negative 145 DEGREES, even though the question does not say so, the answer is the third quadrant.
In what quadrant is cosine negative and cotangent negative?
The second quadrant (top left).
What quadrant does -14-13i lie?
It will be in 3rd Quadrant because cosine and sine both are negative in 3rd Quadrant
Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.

In which quadrant are both x and y negative?
The third (or SouthWest) quadrant.
What are the coordinates of a point that could be in each of the four quadrants?
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
Why is the tangent positive on quadrant III?
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
Is tan theta in the 3rd quadrant negative?
In the third quadrant, both the x and y coordinates are negative. Since tangent is defined as the ratio of the opposite side to the adjacent side in a right triangle, in the third quadrant where both sides are negative, the tangent of an angle theta will be positive. Therefore, tan theta is not negative in the third quadrant.
What quadrant is negative 145?
Assuming the question is about negative 145 DEGREES, even though the question does not say so, the answer is the third quadrant.
Which ordered pair is located in Quadrant III?
Any ordered pair in the third quadrant has negative x and y values. So (-1,-1), for example, is the third quadrant.
What is 240 degree as an angle?
A 240-degree angle is an obtuse angle that measures more than 180 degrees but less than 270 degrees. It is located in the third quadrant of the Cartesian coordinate system, where both the sine and cosine values are negative. In terms of rotation, a 240-degree angle can be visualized as a clockwise turn from the positive x-axis, passing through the second quadrant and into the third quadrant.
