This is a Free Cut & Paste activity for students enrolled in PreCalculus or Trigonometry. The lesson includes 2 trigonometric identities. Students are provided with the scrambled steps on a separate page to cut and paste the pieces in the correct progression to verify the identity. This product is a sample of my PROVING TRIG IDENTITIES product. .
-You can usually prove an identity several different ways, and they are all correct. -The goal is to take one side of the identity and use other trig identities, to convert that side into the other side therefore showing that they are equal.
