Lesson 12: Simplifying Trigonometric Identities

07/22/2016

Aralin tungkol sa pagpapatunay ng mga trigonometric equations gamit ang trigonometric identities. Para mapatunayan na tama ang mga trigonometric equations. Kailangan lang patunayan na ang kaliwang bahagi ng equation ay pareho lang sa kanang bahagi nito. Para magawa ito, kailangan lang ang mga identities at ilang algebraic procedures.

0:57 tanXcosX
1:44 secX/cscX
2:55 (cos^2 x + sin^2 x)/cosx
3:42 (csc^2 x) (cotx) -- cotx
5:12 sect/tant -- tant/(1+sect)
8:11 2cosx + cotx
