differentiate 6x^3 + 2x^2 + 1 = 18x^2 + 4x

To determine stationary point set second derivative to zero

2nd derivative =36x + 4

36x + 4 = 0 therefore x = -4/36 = -1/9

x is -ve t...

Literature is hugely influenced by the contexts in which it is written. If someone said a single statement, such as 'I'm so surprised I got a C in my test' you wouldn't be able to understand what they mea...

A 400m race is a high intensity event which typically last less than one minute, therefore the main energy system used is anaerobic glycolysis. In anaerobic glycolysis glucose is broken down into pyruvate...

Sources are what make history - without them we wouldn't know what actually happened in the past. So, how does this work in an exam setting with a source based question? Relax, first and foremost, you're ...

This is a question which tests your knowledge of how to use trigonometric identities as well as integration. As there is no way to immediately integrate tan^2(x) using well known trigonometric integrals a...
