In what quadrants is tan negative
Web5 nov. 2015 · Using the unit circle we can see that tan (1)= pi/4. Since the "Odds and Evens Identity" states that tan (-x) = -tan (x). Tan (-1)= -pi/4. Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

WebThe cosine of an angle between 270° and 360° is positive, while sine and tangent are negative. If y is such an angle, then. Trigonometric ratios of negative angles. A negative angle implies that an angle is measured from 0° to the clockwise direction of the reference point. If the angle is -50°, then it is 50° in the clockwise direction of ... WebThe graph of cos the same as the graph of sin though it is shifted 90° to the right/ left. For this reason sinx = cos (90 - x) and cosx = sin (90 - x) Note that cos is an even function:- it is symmetrical in the y-axis. sin is an odd function. The graph of tan has asymptotes. An asymptote is a line which the graph gets very close to, but does ...
