[Point 1]
In 'Macbeth', one of the ways in which guilt is presented is through the reoccurring image of blood. In Act 2 Scene 2, the blood on Macbeth’s hands after hi...

To find the equation of the tangent line to the curve y = 2x² - 4x + 3, we have to differentiate. Taking each part of the equation separately, we can calculate dy/dx = 4x - 4. By differentiatin...

y = 1/x^2 is the same asy = x^-2 , now we can use the standard differentiation formula nx^n-1 to gety = -2x^-3y = -2/x^3

Both devices display a similarity in the way that authors use them to emphasize a particular image or heighten an emotion. The difference lies in the fact that, with oxymoronic expressions, the contrast i...

Empirical formula is the simplest whole number ratio of atoms of each element in a compound. With the empirical formula and relative molecular mass, we can determine the actual molecular formula of a comp...
