That's funny! :-) Me too!

The Distracted Student The function equals this-and-that value point zero zero five. The numbers are so precise, so concrete and, so very impersonal. I wish there were some sort of colorful "emotional-abucus." Perhaps it could help us calculate, figure-out, some sort of...

it's okay, it says that in the text...got it from here. thx.

oh okay. So then it is like below? f(2) = 2^5 - 36 = - 4 and f'(2) = 5(2^4) = 80

oh okay, but i am confused because i thought that the fifth root of a number in exponent form was that number raised to the 1/5. I don't understand how it is x raised to the fifth.

Homework Statement Find the 5th root of 36 accurate to four decimal places Homework Equations xn+1 = xn - f(xn)/f'(xn) The Attempt at a Solution First I attempted to write the fifth root of 36 in exponential form as show below: Let the 5th root of 36 = x Let f(x) =...

Thank you nickalh :-) I will have to move on to the next question, but i now see all the good points you have made and appreciate the time and effort you have put into this question to help me. :-)

Hi nickalh! the distances i got at 5 seconds after converting from km/h to m/s where 100m for the train and 75m for the car; and finally, 125m as the z value(the distance between the car and the train at 5 seconds). It may be a coincidence that i got the same answer(-25m/s) for the initial...

in the future, how do i know which unit to convert?

ooops...4m = 400cm so, the result is 20106.2cm^2/min

2cm/min is 5.556X10^-6m/s^2

Firstly, i would like to thank nickalh for showing some compassion for the learner's initial experiences with Calculus and the challenges that it often presents. Second, i have a great deal of respect for the high degree of education and body of knowledge that the contributors to this forum...

I have searched high and low for examples of this type of question, so that i could follow the solution process, but have not been able to find anything. So, unless someone is willing to help me more, i guess i'll just have to seek help elsewhere. It is not that difficult to fly an airplane, or...

I have obviously done as much as i know how to do. Thank you for your help.

Okay, the only formula i know that relates speed distance and time is: v = d/t i have a time of 5 seconds and velocity of 54km/h for the car so, the car's distance is d = v*t = (54)*(5) = 270m I don't know i can't figure this one out
