WebSpherical Trigonometry Rob Johnson West Hills Institute of Mathematics 1 Introduction The sides of a spherical triangle are arcs of great circles. A great circle is the intersection of a sphere with a central plane, a plane through the center of that sphere. The angles of a spherical triangle are measured Web3 The pitfall is that there are two values of A between 0 o and 180 o that satisfy sin A = 0.821575, namely 55 o 14'.6 and 124 o 45'.4. Figure III.3 shows that, given the original data, either of these is a valid solution. The lesson to be learned from this is that all inverse trigonometric functions (sin-1, cos-1, tan-1) have two solutions between 0 o and 360 o.

WebLet us see why 1 Radian is equal to 57.2958... degrees: In a half circle there are π radians, which is also 180°. π radians = 180°. So 1 radian = 180°/π. = 57.2958...°. (approximately) To go from radians to degrees: multiply by 180, divide by π. To go from degrees to radians: multiply by π, divide by 180. Here is a table of equivalent ...
