WebHopefully you understand that an angle of 0 lies ont he positive x axis. On the unit circle specifically it is point (1,0) so it's positive x and 0 y the moment you give it an angle at all x stays positive, and now y is positive too. This is because up until 90 degrees (or pi/2 radians) the circle is in quadrant 1 WebSep 8, 2024 · The coordinates of the corresponding point are (0, 1). Thus, sin(90) = y = 1 and cos(90) = x = 0. The circle will look like this: Fig 5. Unit circle showing cos(90) = 0 and sin(90) = 1. What about tangent(90)? As the cosine measure approaches 0, and it happens to be a denominator in a fraction, the value of that fraction increases to infinity. WebUse a calculator to find sin 39°: d/30 = 0.6293...
