This packet includes notes, examples, and 2 practice tests (and solutions). In addition to the 4 components of trig graphs (amplitude, horizontal ('phase') shift, vertical shift, and period), random comics and math topics briefly appear. The free "preview" file covers sine functions only. The "product" file includes both sine and cosine functions. Plus, word problem examples. If you prefer .docx or .doc format, contact us at mathplane.com. Thanks for visiting, and we appreciate your support!
