Students use formulas to find the differences of the consecutive terms, plot a scatter plot of each sequence, and determine that sequences with common differences (called arithmetic sequences) have scatter plots whose points form a straight line.
- Students will explore sine, cosine, and tangent with respect to the ratios of the sides of right triangles.
- Students will use the TI-Nspire CX II to discover the relationship of these three trig functions.
- Students will solve any right triangle given an angle and the lengths of the opposite side, adjacent side or the hypotenuse.
- Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments.
- sine, cosine, tangent
