Playlist for Trigonometric Identities

President ObaMATH, returns for his last appearances in the "Elliptical Office", for explorations into major concepts within trig identities, including verifying trigonometric identities, trigonometric identities, simplifying trig expressions, solving trigonometric equations, double-angle and half angle identities, sum and difference identities, all based on the pythagorean identities.

Helpful tips:

  • At the top of each video, you can access that lesson's worksheet and quiz.

  • The worksheet contains the exact problems we cover in the video. Just print the sheet and work along with the class.

  • Take the quiz right after the video, to see how well you learned it.

  • To access the worksheet and quiz at any time, simply pause the video.

  • Below, you also have the option of viewing the same playlist on YouTube.
