Find the exact value of tan pi/4
WebKey Concepts. The sine and cosine of an angle have the same absolute value as the sine and cosine of its reference angle. The signs of the sine and cosine are determined from the x– and y-values in the quadrant of the original angle.; An angle’s reference angle is the size angle, [latex]t[/latex], formed by the terminal side of the angle [latex]t[/latex] and the … WebJul 23, 2024 · It is intended to remind us that all trig ratios are positive in the first quadrant of a graph; only the sine and cosecant are positive in the second quadrant; only the tangent and cotangent are positive in the …

WebNov 5, 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.
