# Open Middle: Trigonometric Equation (1)

## 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.
