To find

, we find the first few derivatives and observe the pattern that occurs.

As can be seen above, it can be seen that the continuos derivative of sin (x) is a sequence which repeats after every four terms.
Thus,

Therefore,

.
The unit cost of the fencing and the cost of a bag of mulch together with
the area and perimeter of the garden give a cost sum of $36.5.
Response:
- The amount required to spend is <u>$36.5</u>
<h3>How does the unit cost determine the total cost?</h3>
Cost of the barrier per feet (unit cost) = $0.75
Area covered by one bag of mulch = 7 square feet
Cost of one bag of mulch (unit cost) = $5
From the given diagram, we have;
Area of the garden = 8 ft. × 2 ft. + 0.5 × 8 ft. × 3 ft. = 28 ft.²

Length of fencing = 2 ft. + 8 ft. + 2 ft. + 5 ft. 5 ft. = 22 ft.
- Amount to spend = 4 bags × $5 + 22 ft. × $0.75 =<u> $36.5</u>

1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
