At a stationary point, the gradient/slope of the graph is 0. To find the gradient of y, we differentiate with respect to x.This gives us dy/dx = 2x + 1. Since we want to find where the gradient is 0, we s...

Firstly, the enzyme DNA helicase separates the two strands in DNA by breaking the hydrogen bonds between them. Both of the two strands then act as templates to which free nucleotides attach to. This attac...

Read the poem twice, and a third time aloud. Highlight any language that stands out to you - whether for its tone, technique, imagery, clarity or ambiguity (etc.) Write down your ideas and questions at t...

This is a standard integral of the type f'(x)*f(x)ⁿ. To find the solution, we trial d/dx(f(x)ⁿ⁺¹). d/dx(sin⁵(x)) = 5sin⁴(x)cos(x). this looks similar to the int...
