Question
Identifying direction fields Which of the differential equations
a–d corresponds to the following direction field? Explain your reasoning.
a. y '(t) = 0.5(y + 1)(t - 1)
b. y '(t) = -0.5(y + 1)(t - 1)
c. y '(t) = 0.5(y - 1)(t + 1)
d. y '(t) = -0.5(y - 1)(t + 1)
Expert Solution
Step 1: Given:
Direction field:
To determine which of the differential equations corresponds to the following direction field:
Step 2: Explanation:
From the direction field, it can be observed that the slope is zero at and .
Thus, the equation will be of the form: .
Hence, c and d cannot be the required option.
Now, for and
Thus,
Hence, the correct choice is a.
