Second fundamental theorem of calculus viewed as a transform?

Click For Summary
SUMMARY

The discussion centers on the interpretation of the Second Fundamental Theorem of Calculus as a transform, specifically viewing the function f(t) as being converted into f(x). Vanmaiden confirms that the theorem establishes a relationship between differentiation and integration, stating that the derivative of the integral function F(x) yields the original function f(t). The key equations presented are DF = lim(h→0) (F(x+h) - F(x))/h and If = ∫_a^x f(t) dt, emphasizing the inverse relationship between these operations.

You see this picture of the second fundamental theorem of calculus
32e174d296c019dcd366191d117c3385.png
and you are taught in high school / early college calculus that the t is a dummy variable. However, couldn't you view this as some sort of transform? You convert a function f(t) into a function of f(x). Is this a valid way to view this fundamental theorem of calculus?

Thanks,

Vanmaiden

Yes the theorem is that two transforms are inverse
DF=\lim{h\rightarrow 0} \frac{F(x+h)-F(x)}{h}
If=\int_a^x f(t) dt

The fundamental theorem is that
IDF=F
and
DIf=f
which is not obvious
