This lesson will review some basic trigonometry. The expectation is that you already know this information. I am reviewing it, because I expect you to walk into class the first day knowing it cold. By the end of this lesson you will: - be able to define the sine, cosine, and tangent of an angle using a unit circle - define the sine, cosine and tangent of an angle using a right triangle - memorize SOH-CAH-TOA and be able to use it - memorize the sine, cosine, tangent of all the special angles - define a vector quantity. Deliverables- Please memorize the sine, cosine, and tangent of all the angles in the Trig.Values.pdf OR go to Quizlet.com and use the flashcards to memorize these trig values. - Please complete all of the homework problems assigned. Bring them to class the first day - The first homework is in the attachment called Trig.Special.Angles.pdf - The first homework is the attachment called Trig.Special.Angles.pdf I will only check these assignments for completeness. To actually make sure you know the homework you will have an in-class quiz. In this video we define sine,cosine and tangent using the unit circle In this video we define the sine,cosine, and tangent using triangles At the end I draw a vector but do not define it. |
