Expert Solution
Step 1

Definition: The order of differential equation is order of the highest derivative term in the equation.

The given differential equation is:

tdydy+d6ydt6+cos2 ty=t4

The highest derivative term in the equation is:

d6ydt6

The order of the derivative d6ydt6 is 6.

Hence, the order of the differential equation is:

6
