In which quadrant sin is positive
Did you know?
WebThe letter A in the first quadrant stands for all, as all three of sin 𝜃, cos 𝜃, and tan 𝜃 are positive when the angle 𝜃 lies between zero and 90 degrees. The sine of any angle in the second quadrant between 90 and 180 degrees is also positive. Which of the following points lie in quadrant IV? The correct answer is d. Quadrant IV.
WebIn quadrant one, the A represents all. If any angle 𝜃 lies between zero and 90 degrees, then the sin of angle 𝜃, cos of angle 𝜃, and tan of angle 𝜃 are all positive. We can therefore conclude that the sin of 30 degrees is positive. 30 degrees is actually one of our special angles. And … Web1 - Enter the angle: in Degrees top input.
