    Hi, can you use this method for trig and let u=cosx for example, or not because trig uses lots of trig specific stuff when integrating?

    • @BicenMaths

      No you can use substitution with trig!

    When scaling can we only use numbers not letters aswell for example scale by x/3

      Correct, we can only use numbers/constants for scaling, not variables 👍🏼

    Hello sir, how do you know what you need to substitute the expression by?

    • @BicenMaths
      @BicenMaths  8 місяців тому

      That's the hard part of substitution! They likely would tell you, otherwise you need to try something for the substitution that should simplify the expression you are trying to integrate.

    How do you decide when to use parts and when to use substitution?

    Hi,
    I’m a bit confused on the first minute of this video. When are you can you do reverse chain rule and when can you not?

    how do we know what to put as “u”

    • @ms1414
      @ms1414 Рік тому +9

      use LIATE
      L: logarithms
      I: inverse trig functions
      A: algebra
      T: trig functions
      E: exponentials
      whatevers higher goes as u first

    • @BicenMaths
      @BicenMaths  Рік тому +6

      For substitution, try and pick something for u that would simplify the denominator if it is a fraction - that’s always a good tip!

      ​@@ms1414Incorrect, The LIATE trick is used for integration by parts not u-substitution.
