How to use veclen to find rarius of sphere? 8
tikz
Anonymous 1123 Anonymous 1123
8 The `veclen` function only takes two arguments. However, it is possible to define pgf functions that take arbitrarily many arguments. Existing examples include the `max` function, which in its original version also was restricted to two arguments. Using the the definition of `max` I define a function `Veclen` which takes arbitrarily many arguments.

How to get correct dashed line of this picture? 13

7 As a dirty hack, you could draw the circle two times: once with a solid line and after covering this up, a dashed line on top:

7 This saves and reuses paths either inside or outside the triangle. In order to accomplish the latter, an inverted clip is utilized, which borrowed from [stackexchange](https://tex.stackexchange.com/a/59168).

How can I draw this picture about Volumes of solids? 12

8 This answer comes in three parts, sorted by increasing complexity. The IMHO "best" solution is at the end. Let us start with a very simpleminded proposal, which only works in the limit of small phi, i.e. the second argument of `\tdplotsetmaincoords{<theta>}{<phi>}` needs to be such that the absolute value of its sine is small. Next, a function `R` is introduced that specifies the radius of the volume as a function of `x`. Then the planes and volume are drawn step by step.

5 Another approach could be to test the documentclass during the package loading (caveat: this won't deal with edge cases described in [this comment](https://topanswers.xyz/transcript?room=1259&id=62326#c62326)):

5 Instead of using `\@ifclassloaded` in the key's code, you could test `\AtBeginDocument` which class is used and define the key accordingly:

5 Here is my take at this; I hope this helps a little bit. I renamed `\change` to `\changeBaseline`. It works both in the preamble and in the `document` environment.

Problem with \doublespacing and cases 21

9 You can accomplish this by setting `\baselinestretch` back to `1` inside the definition of the `cases` environment. This is a multiplier for the distance between lines in a paragraph (and also between the rows of the `cases` environment) and it was set to `1.667` by `\doublespacing`.

5 The font is working fine with LaTeX, the problem is rather that the `Bitstream Vera Sans` font you chose, does not contain the rupee symbol. You can see this by inspecting the content of the `.ttf` file:
