Frankly I am a bit put out with your posting images and showing no effort what so ever. The last time, I spent time to help you work out the limits, only to be told "forget it, I have already done the problem".

So in the future, you learn to use LaTex to post your questions, no images. Or else don't expect a reply, especially if you do not show any effort. - February 9th 2013, 07:36 AMPetrusRe: Equation
Hello Plato.

First off, just own up to your mistake, apologize and sincerely work on fixing it in the future. Plato -- who has never charged you or anyone on here any money -- more than deserves the courtesy, don't you think? Don't make excuses. Owning up to mistakes is a sign of one's character and personal strength.

Find a value for such that and call this value . Find another value for such that and call this value .

For example, let and .

and .

is real-valued and continuous on , right?

Now what does the Intermediate Value Theorem say? - February 10th 2013, 05:24 AMHallsofIvyRe: Equation
Do you understand that this problem does NOT ask you to solve 1000=x^2+10sinx?

Yes i did and solved it:) i Will just prove thqt any number on thqt intervall Will give me the solve. I Will not answer like x=3 but i Will prove thqt there is an answer in the intervall. Thats what i did understand
