Transcript


00:0-1	the title of this unit trigonometry is greek for triangle
00:05	measurement . three of the most basic ideas in trigonometry
00:11	are the sign co sine and tangent ratios . The
00:17	sine cosine and tangent ratios can be defined as follows
00:23	. In right triangle abc the sign of angle A
00:28	. Is equal to the ratio of the length of
00:31	the side , opposite angle A . To the length
00:34	of the hypotenuse . So in right triangle abc the
00:39	sign of angle A equals Y over Z . Notice
00:46	that the abbreviation we use for sign is S .
00:49	I . N . Next the co sign of angle
00:54	A is equal to the ratio of the length of
00:57	the side adjacent to angle A . To the length
01:01	of the hypotenuse . So in right triangle abc the
01:06	co sign of angle A equals X over Z .
01:12	Notice that the abbreviation we use for co sign is
01:16	C . E . O . S . And finally
01:20	the tangent of the angle A . Is equal to
01:23	the ratio of the length of the side opposite angle
01:27	A . To the length of the side adjacent to
01:30	angle A . So in right triangle abc , the
01:35	tangent of angle A equals Y over X . Notice
01:41	that the abbreviation we use for tangent is T A
01:45	. N . An easy way to remember the sign
01:49	co sine and tangent ratios is to use the word
01:54	socotra . Sign is opposite over hypotenuse . Co sign
02:01	is adjacent over hypotenuse , and tangent is opposite over
02:06	adjacent .
