Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

24 notecards = 6 pages (4 cards per page)

What is an even function?

back 16

A function that stays the same even when f(x)=f(-x)

front 17

What is an odd function?

back 17

A function where -f(x)=f(-x)

front 18

What are the three Pythagorean identities?

back 18

  1. sin²(θ) + cos²(θ) = 1: This is the most basic identity, representing the relationship between sine and cosine on the unit circle (x² + y² = r², with r=1).
  2. 1 + tan²(θ) = sec²(θ): Derived by dividing the first identity by cos²(θ).
  3. 1 + cot²(θ) = csc²(θ): Derived by dividing the first identity by sin²(θ).
