Differentiate y=e^(x^2+2x)

For this question the chain rule should be used, the chain rule is that dy/du*du/dx=dy/dx. If we say u=(x 2 +2x) and therefore y=e u Then du/dx=2x+2 and dy/du=e u. Then dy/du*du/dx= (2x+2)e u , then we can s...

How do you differentiate 2^x?

We can differentiate this implicitly by writing the question as:y = 2 x Then we take the log of both sides:ln(y) = ln(2 x )Using the rules of logartithms this can be written as:ln(y) = x ln(2)Now we can diff...

differentiate y=(4x^3)-5/x^2

to differentiate this equation we have to do it in two parts because there is a minus sign seperating them in the middle for the first part we first have to multiple the constant by what the power of x is wh...

factorise fully- 8y + 4y2

First of all you need to separate the two numbers you have 8Y and 4y2 then ask yourself what you can divide both these 2 numbers with? so 4 can be divided by 4 and 8 can be divided by 4. so we can divide bot...

What is an easy way to remember how sin(x) and cos(x) are differentiated and integrated?

If you imagine that sin(x), cos(x), -sin(x) and -cos(x) are on a wheel as shown below: sin(x) -cos(x) cos(x) -sin(x) then going clockwise around the wheel you have what each term differentiates to, so sin(x)...
