WebThe value of tan 3pi/4 can be calculated by constructing an angle of 3π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of tan 3pi/4 is equal to the y-coordinate (0.7071) divided by the x-coordinate (-0.7071). ∴ tan 3pi/4 = -1 Download FREE Study Materials WebJul 23, 2024 · Evaluate the following.

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. 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 … WebApr 1, 2024 · We'll use the half angle identity for tangent along with the unit circle to find the exact value of tan(π / 4). There are 3 half angle identities for tangent, but I chose this one (just because!): We just need to find the angle to replace theta. It will be. because. Filling in: Here's where we'll look to the unit circle to find that the rick steves trish feaster
