I think they are all right
And there is nothing much to comment either... Why not try harder ones??
I am currently studying calculus on an open learning basis and was wondering if someone could take a look at these questions and answers I have posted and feed back on my method of working out etc. I am pretty sure these answers are correct but would appreciate any comments.
Question 1:
Obtain for the following expression.
so This is the 1st part.
I then differentiate the inner part of the function so:-
differentiates to 5. This is the the 2nd part.
I then multiply the 1st by the 2nd to get
so
Question 2:
Obtain for the following expression.
so This is the 1st part.
I then differentiate the inner part of the function so:-
differentiates to -2. This is the the 2nd part.
I then multiply the 1st by the 2nd to get
so
Question 3:
Obtain for the following expression.
which is
I then differentiate this to get This is the 1st part:
differentiates to -0.6. This is the the 2nd part.
I then multiply the 1st by the 2nd to get
so
Question 4:
Obtain for the following expression.
so This is the 1st part.
I then differentiate the inner part of the function so:-
differentiates to 3. This is the the 2nd part.
I then multiply the 1st by the 2nd to get
so
As I said at the beginning I am pretty sure I am 100% correct and I agree these are relatively simple questions from a calculus point of view but being new to this subject I was just wondering if someone could make comment please.
Thanks
Derek.
I came across another area which I am trying to get to grips with and was wondering if someone could help
I need to obtain the derivative of
I think I procede as follows.
Finishing up with
or
Another one is Determine if
When the question reads "exp" do I assumeit is refering to the exponential function
I have hunted high and low for similar equations to this to give me some kind of example to work too but come up with more or less nothing so from what I have found I have tried with this. I am probably wrong. Could someone make comment please??
Thanks
Derek
Hello, DRJ!

Hello again
Just a quick query regarding the function.
In my example I think I may have mis read the question.
Is this actually asking me to find of or as you stated as opposed to or are they both the same???
Thanks and happy new year etc
