help.

the value of upper integral bound = 8 (dividend = 4, divisor = 0.5, the lower integral bound = 2, and the big yellow thing, idk. its a weird problem but yeah ill appreciate answers :)

• i dont even think this a valid question? i suck at math im just here for this.

This is probably an exercise to make you understand the role of the variables in integral calculus, and this is a valid math problem imo 🙂
So, you already know three of the four variables on the screen, right ? The only unkown here is that "big yellow thing". This is your variable of integration, if that helps.

In your calculus classes this is often noted $t$ or $x$. For example, the integral of a function $f$ on an interval $[a,b]$ is often noted $\int_a^b f(t)dt$. Here, $t$ is the variable of integration.

In your screen, the variable of integration is not t but "that yellow thing"

(feel free to ping me if you need more explanations)

$\int_2^8 x^2 - 4x dx$
