WebNote that the tangent of a right angle is listed as infinity. That’s because as the angle grows toward 90°, it’s tangent grows without bound. It may be better to say that the tangent of 90° is undefined since, using the circle definition, the ray out from the origin at 90° never meets the tangent line. Exercises 29. WebThe Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known. Finding Sides If you need to find the length of a side, you need to use the version of the Sine Rule …

WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for. WebUnder this situation, we know as long as m (the angle theta) satisfies sin2m=-1, it is the solution and now 2m= 3*pi/2 + 2*k*pi, k is an integer; so m=3*pi/4 + k*pi, k is an integer; we now see that the terminal side of m is the bisector of the 2nd (II) and 4th (IV) … dances with stones
