If I was to do a physics and chem test under exam conditions which I am not at all familiar with, would there be any tutors/past excelling students who would be willing to mark my answers so I have an idea of how I am going? Also, if anyone knows of anyone on the forum who I could specifically...

\int \frac{v}{g-kv} How do integrate this?

\int \sqrt{x^2+x+1} Try this. Its looks are deceiving

How do you prove the reflection property of an ellipse?

Hey, anyone that has completed their MX2 trials, what are the multiple choice questions like? Could someone please give me an example of one so that I know what to expect? Thanks

"A particle is undergoing SHM on the x-axis about the origin. It is initially at its extreme positive position. The amplitude of the motion is 18 and the particle returns to its initial position every 5 seconds." a. Write down an equation for the position of the particle at time t seconds. b...

"A particle is moving in SHM in a straight line. Its maximum speed is 2m/s and its maximum acceleration is 6m/s^2. Find the amplitude and period of motion. " Anyone have an easy way of doing this?

Is a function, f(kx+x) the same as a function f(kx) + f(x)?

Does anyone know where abouts in the book there is a quote about how Genia is crying and Baker feels awkward because as an historian, he made her have those memories, but he wants to console her as a son? it's really good, but i can't seem to find it :/

I just can't seem to see what to do, and it is very frustrating because I know it's relatively easy :P anyway, the question is: "The period of a particle moving in SHM is 6s and its amplitude is 8cm. Calculate its velocity and acceleration (to 1dp) when the displacement is 5cm from the centre...

given a+b+c=1 and a+b+c\geq 3(abc)^{1/3}, prove \frac{1}{a}+\frac{1}{b}+\frac{1}{c}\geq 9 Anyone know how to do this?

I have just proven that \frac{sin\frac{3x}{2}-sin\frac{x}{2}}{2sin\frac{x}{2}}=cosx The question then asks me to prove by induction that cosx+cos2x+cos3x+...cosnx=\frac{sin\frac{2n+1}{2}x}{2sin\frac{x}{2}}-\frac{1}{2} Can someone please show me how to do this? I keep getting to a certain point...

is sin(2x+1)y the same as sin(2xy+y)?

Is anyone good at circle geometry?

I'm sure there's a simple way of doing this, but i just cant see what it is. could someone please do this question with steps that i can follow? thanks The question is: The combined air and road resistance of a car in motion is proportional to v^2, where v is its speed. When the entire engine...

Can two quadrilaterals be said to be similar if, like triangles, their angles are equal?

Ok, so guys, i'm just starting mechanics and I need some help in understanding it. Could someone please answer this question with steps as to how they got the answer so that I can try and follow them? Thanks The question is "A particle of mass 10kg is suspended by two strings of length 3m and...

When determing the volume between a curve and a line by slices, I found i had to integrate in terms of y. Is it possible to just differentiate the original function to get dy in terms of dx and integrate that?

So, what does everyone think about pokemon?

A water sample was taken and the quality of that water was to be tested. The ions present in that water were simply observed rather than recorded as to how many ppm were present. The experiment followed a strict method accurately which simply stated record the observations of the tests. Are the...
