Question

Can anyone please help me with this problem?

$$f(t)\sqrt{t^2+1}$$

find the function if it exists

anonymous · Answer

I suppose the function sqrt(t^2+1) does indeed exist...

anonymous · Answer

but how do you find the function?

anonymous · Answer

U appear to have found it, it's right there...

anonymous · Answer

That is the question

anonymous · Answer

U are saying find the function but u are telling me what the function is?????

anonymous · Answer

that is how the problem is written. ???????

anonymous · Answer

I dont understand what u want me to do, neither does anybody else.

anonymous · Answer

well i am just writing the problem the way it is written.

anonymous · Answer

oops
find the function value if it exists

anonymous · Answer

sorry
i thought I wrote value .

anonymous · Answer

The only thing I can say about the function is that it must be positive by definition.

Else you have to provide a t to enable calculation of a value for that particular value of t.

anonymous · Answer

$$f(t)\sqrt{t^2+1} \cdot \sqrt{t^2+1}^{-1} = f(t)$$ 
which is the "value" of the function at t

anonymous · Answer

it says f(0)= ??????

anonymous · Answer

That-s better....

anonymous · Answer

sorry about that estudier.

anonymous · Answer

So you mean $$ f(t) = \sqrt{t^2+1}$$$$\text{Find $f(0)$}$$

anonymous · Answer

1

anonymous · Answer

$$f(0) = \sqrt{(0)^2+1} = \sqrt{1} = 1$$

anonymous · Answer

Thank you!!!!
