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...
