<p>I need to convert a base 10 int(defined as num) to its base 3 format using a while loop. I would like to store the remainder of the num%3 to a list/sequence/array in maple. Now, if I were to use a sequence, I would need a pre-defined range. How do I solve this issue?</p><p>I need to convert a base 10 int(defined as num) to its base 3 format using a while loop.

<p>I have to find the volume of a solid using the disk/washer method and the shell method. I think I have the first part(disk/washer) right. I think the shell is off. The problem is "the region in the first quadrant that is bounded above by the curve y = 1/x^1/4, on the left by the line x = 1/16, and below bythe line y = 1 is revolved about the x-axis to generate a solid." I am having computer problems so any help is appreciated. Thanks</p><p>I have to find the volume of a solid using the disk/washer method and the shell method.

<p>The problem is The square root of 16-x^2 over the interval [0,-4] 0 being the upper bound, -4 being the lower bound. I have solved 3/4s of this problem but I don't understand what they mean by "Solve the definite integral exactly by geometry". </p><p>The problem is The square root of 16-x^2 over the interval [0,-4] 0 being the upper bound, -4 being the lower bound.

<p>Is there a way to do the following on Maple:</p>
<p>I want Maple to use Jacobi's method to give an approximation of the solution to the following linear system, with a tolerance of 10^(-2) and with a maximum iteration count of 300.</p>
<p> </p>
<p>The linear system is</p>
<p>x_1-2x_3=0.2</p>
<p>-0.5x_1+x_2-0.25x_3=-1.425</p>
<p>x_1-0.5x_2+x_3=2</p>
