To complete this task we use a method called "Completing the square. For this we use a formula (a+b)^2=a^2+2ab+b^2.
Now we see that in the example we have a term x^2 so we put x^2=a^2 so we can ...

P=(3a+5)/(4-a)First of all we need Get rid of the denominator, we do this by multiplying both sides by (4-a)This leaves P(4-a)=3a+5 (as any term multiplied by the denominator leaves only the numerator)Th...

When an action potential reaches a presynaptic cell, it causes voltage-gated ion channels in the membrane to open, which allows Ca2+ to enter the cell. This Ca2+ diffuses into the cell from high to low co...

t = (v - u) / a

f^-1(x)=(e^x-1)/3 g(x)=3/(3x+1)
