AI Thread Summary
To solve for the points where y=0 in the equation, a user suggests utilizing an online grapher for practical visualization. Another participant shares that they determined the roots by analyzing stationary points and behavior as x approaches infinity, concluding that the root is approximately 3.14. This approach avoids the need for complex factorization of the equation. The discussion highlights the effectiveness of graphical methods in solving equations. Overall, using visual tools can simplify finding roots in mathematical problems.

I have done 10)a), but b), I just can't figure it out. I am trying to find at what points y=0, but I just can't do it.

I hope someone can help me.

Thank you,
Stephen.

You've asked in the introductory physics forum rather than the math one, so you must expect to get a practical answer rather than a nice mathematical one! I suggest you type it into the grapher at

and it will show you where the zero is.
 
Turns out. I didn't need it. After I figured out the co-ords of the two stationary points and what happens when X gets inf and -inf then I could see what the roots were and according two the graphics I drew it's about 3.14 so I am pretty sure I didn't have to factorise that damned equation.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
