I'm quite stucked at integrating functions

Click For Summary
SUMMARY

The discussion centers on a beginner's struggle with Integral Calculus, specifically integrating fractions. The user seeks assistance with two integrals: the integral of 3/t4 dt from 1 to 2 and the integral of (x2 + 1) / √x dx from 1 to 2. The forum members emphasize the importance of demonstrating prior attempts and understanding the fundamental concept of integration, particularly the integral of xn dx for integer values of n.

PREREQUISITES
  • Understanding of basic calculus concepts, particularly integration.
  • Familiarity with the integral notation and limits of integration.
  • Knowledge of polynomial functions and their integration.
  • Basic algebra skills for manipulating fractions and expressions.
NEXT STEPS
  • Study the Fundamental Theorem of Calculus to understand the relationship between differentiation and integration.
  • Practice integrating polynomial functions using the formula ∫ xn dx.
  • Learn techniques for integrating rational functions, including partial fraction decomposition.
  • Explore integration by substitution to simplify complex integrals.
USEFUL FOR

Students new to Integral Calculus, educators teaching calculus concepts, and anyone seeking to improve their skills in integrating functions, particularly fractions.

Homework Statement


Hello, I'm new here and it seems that this place would be the right place to post, well, I'm just starting up with Integral Calculus, and I think I'm stucked up with integrating fractions like this one.
Integral of 3/t^4 dt from 1 to 2

2. Homework Equations

yeah I mention ot above, oh, one more example,
integral of x^2+1 all over sqt of x dx from 1 to 2

The Attempt at a Solution


I'm quite stucked up! :(

Thank you!

Hello khael14. Welcome to PF !

Here at Physics Forums, we like to see what you have tried, before we give you help. :smile:

What have you tried? --- or --- What do you understand about integration relative to differentiation?

Where are you stuck?
 
Do you know the integral

[tex]\int x^n dx[/tex]

where n is an integer not equal to -1??
