Coastal erosional landforms are commonly found in high energy environments, where large waves, strong winds and tidal currents drive erosion. There are a number of different mechanisms which cause erosion...

As a history student, I was rarely intimidated by the thought of a big marker business question unlike the rest of my peers. However, as time progressed throughout my Alevel study I realised just how easy...

Differentiate implicitly on both sides with respect to x to get: 2=cos(y) • (dy/dx). Divide by cos(y) on both sides to get: dy/dx=2/cos(y). Use the trigonometric identity cos^2(y)+sin^2(y)=1 rearranged to...

to find dy/dx, multiply each item by the power of the x, and then decrease the power of the x by 1.Step 1 : 2x^2 -15x (multiplying by power of x)Step 2 : 2x^1 -15x^0Therefore:dy/dx = 2x ...

Book twelve of the Aeneid, the final book of the epic, culminates in a final act which epitomises the relationship between furor (rage) and pietas (duty to family, gods and state) which has been central t...
