Creation of this resource was inspired by this original Open Middle exercise created by Kevin Rees:

Directions: Using digits 1-9 AT MOST ONE TIME EACH, type a digit in each box to make the trigonometric equation below true. Build and modify as much as you need.

Directions: Using digits 1-9 AT MOST ONE TIME EACH, create another valid setup that is ENTIRELY DIFFERENT from the one you created above.

Directions: Using digits 1-9 AT MOST ONE TIME EACH, create another valid setup that is ENTIRELY DIFFERENT from the two setups you created above.

What is the LOWEST POSSIBLE OUTPUT (value that both sides equal) you can create given the constraints of this problem? Create a setup that shows this below.

What is the HIGHEST POSSIBLE OUTPUT (value that both sides equal) you can create given the constraints of this problem? Create a setup that shows this below.
