07/22/2016

Aralin tungkol sa pag-evaluate at pag-solve ng mga trigonometric equations gamit ang mga natatanging trigonometric identities. Bawat trigonometric function ay mayroong mga trigonometric identities. Gamit ang mga ito, maaring ma-evalute ang mga values ng iyong variables. 

0:40 sin^2 - cos^2 = 0
3:00 cos^2 x + cosx = sin^2 x 
5:17 3tan^2 x = 2sec^2 x + 1
