## Line Integral 2D and 3D...

Maple 2020

I want to create a 2D and 3D graph of the following question. Evaluate F xy+y+z along the curve r(t)=2ti+tj+(2-2t)k, 0<=t<=1 I found the line integral to be 13/2. I am just stuck on how to graph this in 2D and 3D.

Thank you all in advance! I enjoy learning all the new tricks in Maple from you all.

## ConvertingCartesian to Polar Plots...

Maple 2020

I have been having difficulty with plotting these graphs from Cartesian to Polar. I know that with double integrals there is an inclusion of r when you go from Cartesian to Polar. I think my graph of the function being integrated is correct. I am having difficulty with the command for the shaded region. I know with Cartesian, I can use inequal command to get the right shaded area. Will this command work with polar coordinates?

I attached the Maple worksheet.

Thank you all for help in advance!

## Creating a gradient with one level curve...

Maple 2019

I have been stuggling with this for a few hours. I have my function 4x^2+9y^2. I have my point (2,1,25). I found my gradient to be 16i+18j. I want to plot the level curve that contains the point (2,1,25) and the gradient together.

I know how to graph multiple level curves but not one.

## 3D Graph of Parabloid...

Maple 2019

I am so sorry for all of the questions. I am getting extremely frustrated with Maple.

I want to plot a 3D rendering of 4x^2+9y^2 but I want the full paraboloid to show. However, all I keep getting is cut off versions.

## Why is this happening?...

Maple 2019

I want the legend to be produced to look like the third to last example. https://fr.maplesoft.com/support/help/Maple/view.aspx?path=plots/contourplot

However, mine keeps coming out like this.
