WebTangent will be positive because a negative divided by a negative is positive.) The final quadrant is the fourth quadrant, and there, all x values are positive, but all y values are … 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: scratchpad wiki tugboat as lightning
What trig functions are positive in which quadrants?
WebFor example, If the line intersects the negative side of the x-axis and the positive side of the y-axis, you would multiply the length of the tangent line by (-1) for the x-axis and (+1) for the y-axis. You will find that the TAN and COT are positive in the first and third quadrants and negative in the second and fourth quadrants. WebMar 27, 2024 · Any angle whose terminal side is in the third or fourth quadrant will have a negative y −coordinate, and any angle whose terminal side is in the second or third quadrant will have a negative x −coordinate. Figure 2.3.5.3. In either case, the minimum value is -1. For example, cos180 ∘ = − 1 and sin270 ∘ = − 1. WebJan 30, 2024 · Quadrant 4 is positive for the cosine function (the x-coordinate) and negative for sine (the y-coordinate) and tangent (divide y/x).
