Question 5: prove that it’s =0

Proof in explanation.

Step-by-step explanation:

I'm going to attempt this by squeeze theorem.

We know that is a variable number between -1 and 1 (inclusive).

This means that .

for all value . So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.

By squeeze theorem, if  

and , then we can also conclude that .

So we can actually evaluate the "if" limits pretty easily since both are continuous  and exist at .

.

We can finally conclude that by squeeze theorem.

Some people call this sandwich theorem.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?
