Answer:
option (d) is correct.
The mid points of the line segment whose ends points are (-2,-2) and (4,6) is (1,2)
Step-by-step explanation:
Given: end points of a line segment as (-2,-2) and (4,6)
We have to find the mid points of the line segment whose ends points are given.
Mid point formula is stated as ,
For a line having end points as , the mid point can be calculated as,
Here,
Substitute in mid point formula, we get,
Solving further , we get,
Thus, the mid points of the line segment whose ends points are (-2,-2) and (4,6) is (1,2)
Thus, option (d) is correct.
Divergence is easier to compute:
Curl is a bit more tedious. Denote by the differential operator, namely the derivative with respect to the variable
. Then
