Definite Integrals

Definite Integrals

1. 1. First you need to know this formula A=∫_a^b▒f(x)dx the values of a and b are your integration limits the f(x) is the function you are given and your dx is your ∆x

   • 2. Then you integrate you f(x) and at the end you put the evaluation for b and a
     • 3. You solve twice the f(x) solving for each value of your integral limits (first you substitute the value of b and then the value of a)
       • 4. Then you subtract the result of A_t=A_b-A_a
         • 5. Finally you express the result of At with u^2
