Answer:
Step-by-step explanation:
The unit vector for a nonzero vector, say u, in the direction of u is given by:
û = ---------------(i)
Where;
|u| = magnitude of vector u
From the question;
u = (4, -4)
First let's calculate the magnitude of u as follows;
|u| =
|u| =
|u| = =
Now, substitute u and |u| into equation (i) as follows;
û =
û =
û =
Therefore, the unit vector is
The value of the and
are 0 and 1.153 .
Limiting Value of a Function. The function's limit is the value of the function as its independent variable, such as x approaches a certain value called the limiting value. For simple equations, this is similar to finding out the value of y when x has a unique value.
Given that,
f(x) =
First to calculate the limit value of the given function at x=0.
=
= 4×0×1 (∵ cos0 = 1)
= 0
Similarly,
=
= 4××cos
= 4××
(∵cos60° =
)
= 1.153
Hence, The value of the and
are 0 and 1.153.
