Answer:
Step-by-step explanation:
Given A = 5i + 11j – 2k and B = 4i + 7k, the vector projection of B unto a is expressed as
b.a = (5i + 11j – 2k)*( 4i + 0j + 7k)
note that i.i = j.j = k.k =1
b.a = 5(4)+11(0)-2(7)
b.a = 20-14
b.a = 6
||a|| = √5²+11²+(-2)²
||a|| = √25+121+4
||a|| = √130
square both sides
||a||² = (√130)
||a||² = 130
<em>Hence the projection of b unto a is expressed as </em><em></em>
In this exercise, we have the following functions:
And they are defined for all real numbers x. So we have to write the following expressions:
First expression:
That is, we subtract s(x) from r(x):
Second expression:
That is, we get the product of s(x) and r(x):
Third expression:
Here we need to evaluate:
First of all, we find the sum of functions r(x) and s(x):
Finally, substituting x = -2:
