What are some applications of integrals in science?

Question

i know there used in physics, engineering, etc but what specifically?

Answer 1

reimann sums of data from a concentration*time profile can tell me about total drug exposure which can help me figure out which is the best dose to work with, what effect that dose will have, and how long the effect will last; this is called pharmacokinetics.

Answer 2

Integrals are mainly used in Physics.You will need to know how to solve integrals mainly when you are solving derivations where you need to know the values in accordance with time period simply!

Answer 3

You might want to find the amount of fluid moving over a particular surface(Integration of a vector field over a surface), solve differential equations using an integral transform(Laplace transform), analyze data using a Fourier transform(This gives you information about the frequencies which make up a signal) or solve a simple kinematics problem.

Integration and differentiation are used everywhere.
