Planet Mars

Exercises 1.4



For part (a), I must evaluate each interval [a, b] this way:

Let A(t) = average velocity

A(t) = [(10(b) - 1.86(b)^2] - [(10(a) - 1.86(a)^2] ÷ (b - a)

For part (b), I must find derivative of the given function and then evaluate when t = 1.

Yes

 

use


b. yes
The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t.

 

I will take mt time through the calculus textbook. I will do question 6 parts a and b and show my work here tomorrow.

 

Part (a)



Part (b)

 

correct

 

Thank you.

 

Yes, that is what you are to do. Why haven't you done it?

 

I posted this and other calculus 1 questions when I thought it was a good idea to study this course and precalculus at the same time. Bad idea.
