Example Question #121 : How To Find Position

The velocity function of a particle and a position of this particle at a known time are given by v(t)=sin(t^2) p(0)=4 . approximate p(0.6) using Euler's Method and three steps.

Possible Answers:

4.024

4.032

4.016

4.040

4.008

Correct answer:

4.040

Explanation:

The general form of Euler's method, when a derivative function, initial value, and step size are known, is:

$y_n=y_{n+1} +\Delta x f'(x_n,y_n)$

In the case of this problem, this can be rewritten as:

$p(t_n)=p(t_{n+1}) +\Delta t v(t_n)$

To calculate the step size find the difference between the final and initial value of and divide by the number of steps to be used:

$\Delta t = \frac{t_f-t_i}{Steps}$

For this problem, we are told v(t)=sin(t^2) p(0)=4

Knowing this, we may take the steps to estimate our function value at our desired value:

$\Delta t = \frac{0.6-0}{3}=0.2$

p_0=4;t_0=0

p_1=4+(0.2)sin(0^2)=4

p_2=4+(0.2)sin(0.2^2)=4.008

p_3=4.008+(0.2)sin(0.4^2)=4.040
