May I know how to write this one? @Zarkon @asnaseer

Answer 1

I particularly want to know how one can make that vertical line you can see on the rightmost.

Answer 2

\[ \left(\large{2\over 5}t^{5 \over2} - {4 \over 3}t^{3 \over 2}\right)\LARGE\mid^{4}_{0}\]Hehe, got it.

Answer 3

\[\text{\[\left.\left(\frac25t^{5/2}-\frac 43 t^{3/2}\right)\right|_0^4\]}\]
\[\left.\left(\frac25t^{5/2}-\frac 43 t^{3/2}\right)\right|_0^4\]

Answer 4

@UnkleRhaukus that's even better!
