Not sure how to do task 1 and 2.
Please provide solutions with explanations

Please review your equations - I think typo/s are there.

You have not defined your variables - what is 'x' & 'y'? What are those?

The owl would be winking when the eye-lids are in "opposite" phases. (one open and other closed - at the same time)

The owl would be blinking when the eye-lids are in "same" phases. (both eye-lids are closed- at the same time)

y are the minutes and x is the cm of eye lids. Please review the task above for clarification.
