Le Chatilier's principle states that, if a change is made to a system at equilibrium, the position of equilibrium will shift to oppose that change. If you increase the temperature of a system where the fo...

To maintain the equality everything that is done to one side needs to be done also to the other. First, we square both sides to get rid of the power on the right-hand side. What we get is p^2 = (x+y)/5. N...

Having a plan with regards to the mark scheme is the first step before committing to any project as you can easily get lost in the creative process and then before you know it, the deadline is in a few da...

First, expand the brackets. This will give us 10x^3/2 - 20x. Now to integrate this expression we have to increase the power of each term by one and then divide them by the number which becomes the new pow...

First we need to find the derivatives of x and y in terms of t. dx/dt can be found using the chain rule. Differentiating the inside of the bracket gives us 2. Multiplying the outside gives -2sin(2t) (Deri...
