WebIn the first quadrant, all functions are positive, in the 2nd quadrant, only sin and cosec are positive, in the 3rd quadrant only tan and cot are positive, whereas in the 4th quadrant only cos and sec are positive. Thus, we can tabulate the signs of different trigonometric functions in different quadrants as follows: Read more: WebSo the question you mention the trigonometric was positive in 4th quadrant was cosine. While ones that were negative were sin and tan. Alternatively know that cos theta = x, sin theta = y, tan theta = y/x and then you could figure out where each trigonometric function is positive based on y and x values in the unit circle. So in the 4 quadrant ...
WebCosine is also negative in quadrant III. Note that a calculator will only return an angle in quadrants I or II for the cosine function, since that is the range of the inverse cosine. See Figure \(\PageIndex{2}\). Figure \(\PageIndex{2}\) So, we also need to find the measure of the angle in quadrant III.
