none... I'm programming it... its suppose to find any function

Hi, I'm having trouble doing my work where I have to find the Taylor Approximation of function. My real work is the program this thing when the function, x, a, and ErrorBound is given. I don't knwo what to do with the ErrorBound to get n, where n is the number of terms. do i make any sense...

seems simple enough... just substitue the first and second integrals using the y and x as if they're values and equate them to each other like you have done. find y'. may have to use implicit differentiation. then equate to 0

why not use venn diagram to check?

i'm sorry but i don't get what you mean

oh ok. that makes sense now. its just the textbook is so bad that it doesnt' say that the normal force can be affected.

Question: A force of 50N acting at 37degrees above the horizontal pulss a block along the floor with constant velocity. If the coefficient of friction between the blocck and the floor is 0.2, what is the mass of the block? the answer in the book is 23.4kg but when I did it I got 20.3kg...

aslo the train is a force on it and i have ot find the acceleration of the train that would give that particular force so it slides down at 9.0m/s^2

also i don't know know the mass of the block

how do you know that the friction is that?

I'm really stumped with this question. A block is held against the front of a vertical wall of a railroud car. The coeffiecient of friction between the block and the wall is 0.4. When the train betgins to accelerate the block is released and begins to slide down the wall with an...

for part a i got 102.4 J. does that look right?

what part of the question are you referring to?

this is what i got so far. W = F * distance so by the diagram I got: W = 25 N * 5m * cos 35 but i know that's wrong... i dont' know how i incorporate teh mass

A cable car is operated on a slope 1000 m long making an angle of 30deg. with the horizontal. The cable car moves up the slope with a speed of 3.5 m/s and carries 20 persons of average weight 600 N. What power is needed?
