1. (10 points) When verifying identities, common formatting/structure mistakes are: (1) Skipping show- ing the side of the identity you start with; (2) Not including equal signs between steps: (3) Not including the input of the functions (i.e., writing tan instead of tanz): (4) Assuming the identity is true before verifying it (i.e. writing what you are trying to get before you get there) (5) Writing the identity and doing things to both sides, like you were solving an equation....
