Representing Rotations

Keeping in mind these basic rotations :

Don't let the extra 0s and 1s bother you ! We only need them for scaling purposes which we didn't arrive yet, and for our cases, they will always be 0s and the last column and last row will always be 1.

Rotation Examples

Please try to fill the right rotations required to pass from figure 1 to figure 2. The highlighted axis are always looking OUT of the page (Towards you).

Please enter values such as "cos 90", "-sin 90", "sin -90", "-cos -90", "sin 90 + cos -180" or "cos 90 * cos -90", do not actually calculate them and make sure to not leave any spaces.
