Begin by reading the poem all the way through. How does it sound in your head? Listen for alliteration, assonance, dissonance. Where is it smooth and where is it jarring? Think about the stresses of the w...

The action potential arriving at the presynaptic membrane causes the voltage gated calcium ion channels on the presynaptic membrane to open. This causes an influx of calcium ions into the presynaptic neur...

f(g(x))=2(cx+5)+c

fg(x)=2cx+10+c

2cx=6x

2c=6

c=3

10+c=d

d=13

Multiply whole equation by 2

6y + 4x = 12y - x

Take 6y from both sides

4x = 6y - x

Add x to both sides

5x = 6y

divid both sides by 5

x = 6/5(y)

Differentiate equation: f'(x) = (2ax + b) ln(x + (1+x^2)^(1/2)) + ((a + 2d)x^2 + (b + c)x + (c+d)) (1 + x^2)^(-1/2).

Select correct values for constants to get:

i) x ln(x + (1+x^2)^(1/2)) - ...
