@MartinSleziak new-tag The pdf is still there - it was used in another question. This time in the meaning probability density function.

Q: Limits for the density function

Rachel12$f_{X,Y}(x,y)=2$ for $0 < x < y < 1$ & 0 otherwise. Find the density function of $Z$ where $Z = X + Y$. My textbook has this formula: $f_Z(z)=\int f_{X,Y}(u,z-u)\;du$. Apologise for the formatting. The solution sets the limits as $0 < u < \frac{z}{2}$ if $0 < z < 1$ and $z-1 < u < \frac{z}{2}...

There already exists a tag called density-function. The tag-excerpt says: "For questions on using, finding, or otherwise relating to probability density functions (PDFs)"
@quid specific-tag tag-synonyms The tag pdf was created recently. Do you think it's better simply to remove? Or would it be better to create a synonym pdf $\to$ density-function?

@MartinSleziak In this question (pdf) has already been replaced by (density-function): math.stackexchange.com/posts/3595286/revisions
