Hello! I have a function ##f(t)## such that ##\int_a^b{f(t)dt}=f_0##. Is there a way to calculate (or bring it to a simpler form) ##\int_a^b{f(a)e^{t}}dt##? Thank you!
As written, ##\int_a^b{f(a)e^{t}}dt = f(a)[e^b - e^a]##.BillKet said:Hello! I have a function ##f(t)## such that ##\int_a^b{f(t)dt}=f_0##. Is there a way to calculate (or bring it to a simpler form) ##\int_a^b{f(a)e^{t}}dt##? Thank you!
Ah sorry, the questions should be about ##\int_a^b{f(t)e^{t}}dt##etotheipi said:As written, ##\int_a^b{f(a)e^{t}}dt = f(a)[e^b - e^a]##.
It should be ##f(t)##. It is not an exercise, it is something obtained from a physics experiment, but I would say that yes, the function is differentiable. I can't say that I had many ideas, I was hoping there is probably some formula I don't know about that can be applied, as there is not much to do here with basic integration techniques.trees and plants said:May i ask : does the exercise say that ##f(t)## is differentiable? the second integral contains##f(a)##?or perhaps it is ##f(t)##? what is your effort so far?
I don't think the integral can be evaluated without knowing more about f(t).BillKet said:Ah sorry, the questions should be about ##\int_a^b{f(t)e^{t}}dt##
An integral involving an exponential function is a mathematical expression that involves the integration of a function with an exponential term, such as e^x, in its equation.
Simplifying integrals involving exponential functions can make them easier to solve and understand, and can also help in finding solutions to real-world problems in fields such as physics, engineering, and economics.
Yes, there are various techniques for simplifying integrals involving exponential functions, such as substitution, integration by parts, and partial fraction decomposition. The method used depends on the specific integral and its properties.
While some calculators may have functions for solving integrals, it is important to understand the concepts and techniques behind simplifying integrals involving exponential functions, rather than solely relying on a calculator.
Some tips for simplifying integrals involving exponential functions include using properties of exponents, recognizing patterns and common integrals, and practicing regularly to improve problem-solving skills.
