hi can you just explain what the actual difference between writing dy/dx and f'x if there is any or is just different ways of writing the question and they ultimately mean the same thing (which is that you have to differentiate)...thanks
+Tobi Akinyemi i think i now understand, its simply the value of x in the second derivative equation, and nothing to do with the actual value of x in the first equation.
One application is to be able to tell whether a stationary point is a max, min or point of inflexion. There are many other applications but this you are likely to meet at this early stage.
As per usual, excellent video. Thank you
there is no difference. If you are given f(x)=... then use f ' (x). If given y= ... then use dy/dx
i just watched your other clip ...it has answered my question...thanks very much!! :D
Better that my teacher
Thank you
Understandable thankyouu❤️
It would be great to use an exam question, but overall awesome vid
Is this what is meant by partial differentiation?? or do you have a separate video on that ???

there is no difference.
for the 3rd question, is the value of x (4/18), the actual value of x in the equation or some sort of value for a gradient.

Thank you❤
You are very welcome!
@@ExamSolutions_Maths What a legend.
Hi, what is the purpose of 2nd order differentiation?
