First we should find the gradient of the line perpendicular to PQ by rearranging the equation.5x+3y=113y=11-5xy=11/5 -5/3xy= -5/3x + 11gradient is -5/3.We know that the gradients of perpendicular lines mu...

'Por' and 'Para' often cause confusion because both can be translated in English as 'for'. The best way I have found to understand this is using the example of presents. Consider the phrase 'I a bought th...

Stationary points occur when f'(x) = 0. To find this, we differentiate f(x) to get f'(x) = 12x^3 - 24x^2. We know that at the stationary points are when f'(x) = 0. so we know that 12x^3 - 24x^2 = 0. We ca...

The theme of power and lack of it is utilised expertly by Shakespeare and made a prominent motivation for the ensemble of characters in the play. It helps give depth to characters, mirror reality and pres...
