Annual Calculus Questions

Find f'(x) (the derivative of f(x)) if f(x) = 7x^3 - 2x^2 + 4x - 5.

21x^2 - 4x + 4

The integral of 3x^2 - 4x + 1 equals x^3 - 2x^2 + x. Is this always correct?
No

Find dy/dx if y = e^a and a is constant.
0

If f(x) = x (ln x), find f'(x).
1 + ln x


If the velocity of a particle at time t is represented by the equation v(t) = 8t + 2, find the position of the particle at time 3 if the position at time 0 is 0.
42

An object is in freefall. It remains in freefall for 5 seconds before it hits the ground. How high was the object when it first started falling if its starting velocity was 0? (Acceleration due to gravity is -9.8 meters/second^2).
122.5m

If f(x) = (sin x)/x, what is the limit of the function as x approaches zero?
1

Re: Annual Calculus Questions

Hi;

I agree with the first six.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Annual Calculus Questions

May I ask what course this is for? It seems like your work is a mixture of calculus and mechanics -- do you do any statistics?

Re: Annual Calculus Questions

Not statistics. I am taking a mechanical engineering course along with a physics course.

Re: Annual Calculus Questions

Are there any really easy problems? You can always make a mistake. Last mistake I made I did not copy the answer correctly after I found it!

Re: Annual Calculus Questions

Some people when faced with easy questions or tasks make mistakes. In competition we have a name for people like that.

Re: Annual Calculus Questions

Loser.

When someone is capable of beating weaker opponents consistently we say he is a good fishkiller. Same thing with questions. Your success in life is going to be determined by how you deal with the easy stuff. That is where you show your concentration and consistency.

Re: Annual Calculus Questions

School teaches you about winning the big ones and being a hero. I know many people who are capable of slaying a dragon but then they lose to a much weaker obstacle. They lack consistency, they lack focus. They can not succeed.

Re: Annual Calculus Questions

Then there are the occassional few who take advantage of school and retain their knowledge forever (i.e. a guy named bobbym).

Re: Annual Calculus Questions

The two best mathematicians in my opinion on this site are both self taught!

Re: Annual Calculus Questions

Those being? You and MIF? In terms of the few best on this site (in my preference): You, MIF, Stefy. Self-taught or not.... I would consider myself self-taught, as I elarn nothing from school (as of now). However, it is challenging. Visiting calculus-tutoring sites when I was 9...What a bother!

Re: Annual Calculus Questions

Certainly not me. I have carelessly said something I should not have and apologize for mentioning those two people.

Always be meticulous in your actions! But how is a bad thing? Mind discolsing those two sacred names of master mathematicians on this very forum?

Re: Annual Calculus Questions

If I mention them I insult others who may feel left out. There are many talented people here. The best part is most of them do not know it!

Anyone smart enough to think that they deserve to be held in great self-esteem by you are smart enough to honour the skils of others.
