Neurones are nerve cells that carry information as tiny electrical signals. There are three different types of neurones, each with a slightly different function: sensory neurones carry signals from recept...

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...
