Thanks very much for your input. I will try this problem again, this time with a better understanding!
The reason geometry is not allowed for this problem, is because this is not actually from a geometry class. This problem is from one of my modules on inequalities, sets and logic (to summarise).
This is the solution:
Unfortunately I was not able to make sense of it, but perhaps it makes more sense now that I saw all the replies here.
The values of the linear functions which determine the sides of the triangle ##a(x,y) = 2x+y-2##, ##b(x,y)=2x-3y-6##, ##c(x,y)=x-y-1## opposite to...
"Let's take the two points we are given, P and Q, and add the origin O as well to give us more data. Now, taking the lines in the order given, we plug in the x value of our point and say whether the y value is greater than or less than the expression in x on the RHS:"
I am not sure what to...
Yes, I believe this would work, although perhaps more complicated. The solution refers to a method like the one stated by several threads above, however it is written in a way that does not really make sense on its own. The only thing I can tell is the use of some inequalities.
That's why I...
Okay so I have tried to work this out like you said, although a bit confused. Please correct me if I did any mistakes in here.
First rearranged the equations in the form ##y=mx+c##:
##
\left.\begin{matrix}
y= -2x+2\\
y=-\frac{2}{3}x+2\\
y=x-1
\end{matrix}\right\}triangle
##
Then, finding the...
Hmmm... This is the website, in case you want to have a look: https://www.ukessays.com/essays/mathematics/how-can-integral-calculus-be-derived-and-applied-to-find-the-volumes-and-surface-area-of-complex-three-dimensional-objects.php
I can't figure out what kind of geometry could have been used...
I've never actually done this, so I was wondering if someone could show me how this is done. One way I tried was by simply using ##cos^{-1}## in order to cancel the cosine, but that gave me a different value, so I assume this is not how you are supposed to do this.
--> I know I am supposed to...
Yes, I understand what you wrote. However, I feel like this mainly applies to wheels that deform on the surface, such as a deflated tire for example (correct me if I'm wrong), so how can you apply any equation to find the Frictional Force for basically a hard wheel on another surface? (besides...
Thank you! On the website you have linked in your comment above I have found the following equation:
$$F=\frac{Nb}{r}$$
Would this then give me the force due to the rolling resistance directly? That means I wouldn't need to use the equation above? Because essentially I am trying to find out the...
