    My professor doesn't explain what he is doing and literally just says
    "This is a two, then we have a 6, then we put it over here."
    Its so frustrating, so thank you. This really helped me.

    If I don't take sin(x²) and instead I use (sin²x) and solve it then I get a different answer.
    For 1st cond. Sin(x²)= 2 sinx. cosx
    And 2nd cond. Sin²x = d/dx ( sin²x)= cos²(x). 2x
    Which one is correct. ?

    • @joelprestigiacomo4093
      @joelprestigiacomo4093  3 роки тому

      Both are wrong. First would be cos(x^2)*2x
      Second would be 2sin(x)cos(x)

    i still dont understand because what about those ones with the power more than 2 e.g tan^4(5x-1)

    • @joelprestigiacomo4093
      @joelprestigiacomo4093  9 місяців тому

      It would be 4*tan^3(5x-1)*sec^2(5x-1)*5
      You do the power rule with tangent, then take the derivative of tangent (sec^2) then take the derivative of 5x-1, being 5.

    @jaynufable1164 3 роки тому

    I just realized there's an easy way to solve that sin^2(3x).
    You just expand the equation to sin(3x) × sin(3x) then apply the rule on particles. The d(uv)/dx rule. Then you just to add 3sin(3x)cos(3x) + 3sin(3x)cos(3x). Same answer, easier method.

    • @joelprestigiacomo4093
      @joelprestigiacomo4093  3 роки тому +2

      Yes, definitely easier in that sense. My goal was to show the overall method and not necessarily the most efficient way to solve this particular problem. This method would certainly be the best if the exponent was negative, or rational and not 1 or 2.

    Okay this was clear but what confused me is, why on the first example he directly turned sin2x into 2cos2x without leaving sin there but on the second example he kept sin as 6sin3xcos3x?

    • @joelprestigiacomo4093
      @joelprestigiacomo4093  4 роки тому

      If you are finding the derivative of just sin(x) or sin(2x) then the expressions simply transform into cos(x) or cos(2x)*2. If the expression has an exponent other than 1 like in my second example, you use the power rule on the trig expression so the original will remain with a lowered exponent and its derivative will appear and chain to the end.
