The speed was 60 kmh for the first 60 km and 5 kmh for the last 10 km.
. In Euclidean geometry Ptolemys theorem is a relation between the four sides and two diagonals of a cyclic quadrilateral a quadrilateral whose vertices lie on a common circle. This method is wrong not because the method itself is wrong but because it doesnt apply to this situation. Thats why youll find loads of practice problems with solutions all carefully curated by Jenn.
Its one thing to watch the video lessons. Ptolemy used the theorem as an aid to creating his table of chords a trigonometric table that he applied. Spherical trigonometry is the branch of spherical geometry that deals with the relationships between trigonometric functions of the sides and angles of the spherical polygons especially spherical triangles defined by a number of intersecting great circles on the sphereSpherical trigonometry is of great importance for calculations in astronomy geodesy and navigation.
The naive solution is to average the speeds using the add-and-divide method taught in junior high school. The theorem is named after the Greek astronomer and mathematician Ptolemy Claudius Ptolemaeus. Youll learn more in less time and know exactly what to work on.
But making sure you can apply what youve learned takes practice.
