Homework Help Overview

The problem involves a particle moving along the x-axis with a velocity function given by v(t) = sin(x²). The task is to find the total distance traveled by the particle from time t=0 to t=3, given that the initial position at t=0 is x(0)=5.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need to integrate the velocity function to find displacement, with one suggesting the use of a Taylor series for approximation. Others question the sufficiency of the velocity graph for determining distance and reference integral definitions.

Discussion Status

The discussion is ongoing, with various approaches being considered, including integration and series expansion. Participants are exploring the implications of the provided graph and the definitions related to distance and integration.

Contextual Notes

Some participants express uncertainty about the difficulty level of the problem for an AP Calculus AB class and mention the limited experience with integration techniques, such as substitution.

Homework Statement


A Particle Moves along the x-axis so that its velocity v at time t \geq 0 is given by v(t)=Sin(x^{2}). The Graph of V is shown above for 0 \geq t \geq \sqrt{5\pi}. The Position of the particle at time t is x(t) and its position at time t=0 is x(0)=5

Homework Equations


Find the total Distance traveled b the particle from time t=0 to t=3.


The Attempt at a Solution


Homework Statement


We just started on integration so i figured we would need find the displacement equation by integrating the velocity equation, which would be finding:
\int Sin(x^{2} dt [0,3]. From here i have no idea how to do the equation since we're only 2 weeks into integration and have barely touched \mu Substitution

The only way I can see to do it is to take the taylor series of sinx and replace all the x's by x^2 and then approximate the terms.
 
oh thanks, in your opinion do you think that this problem is quite difficult for an AB AP Calculus Class?
 
If the graph of the velocity is given, can you use this alone to find the distance? Remember the original definition of the integral of a function!

[also remember that as in real life, not all information available to you need be relevant.]

Oh. Are you referring to a of a Rieman's Sum approach to solving the equation by means of RRAM/MRAM/LRAM, Simpsons, Trapezoidal rule?
