On the practice questions, there is a derivative that is "Y=x^1/3" or y=x tot eh one third. They say the answer is 1/3x^-1/3. Why isn't that 1/3 x^-2/3, if f(x^n)=nx^n-1?

I swear I just wana say that People like me; students like me who can not afford 50 or 60 bucks for an hour and are so keen to learn and do good in exams so we can have better grade for class...are struggling so HARD!! Seriously
My Heart aces to say that the system of Education in United States is not what I hoped for when I came here.. Professors simply just DONT CARE!! (talking about Uni Level tho) .. All they care is to be ahead of syllabus.. and dn't get me wrong I am PAYING for this but this does not HURT because the explanation was so beautiful that I actually understood!! and it is sooo SAD when you pay 25,000$ an year un UNI but its not worth it because there is no such thing TEACHING happening and there is no such thing LEARNING happening...!!  A humble THANK YOU from a struggling Immigrant Student (I really had a lot bottled up on my chest)

I just have to say that in Example 3 problem (i) your detailed explanation of (7x) and the constant 3 blew my mind. When you forced it into the structure of the power rule a switch flipped for me. Thank you so much for your ultra detailed explanation.

Derivatives, part 1; the power rule, Example 3 is not working at approx. 14:05...... Can you please fix this,
Thanks




The Power Rule

  • Check whether your instructor wants you to know the proof of the Power Rule of Differentiation.
  • Practice carrying out the Power Rule on problems involving negative exponents and fractional exponents.
  • The derivative of a sum (or difference) is the sum (or difference) of the individual derivatives.
  • A constant factor can be factored out in front of a derivative.

The Power Rule

Find the derivative of y = 2x3 + 5x2 + 7x + 11
  • dy = [d/dx] (2x3 + 5x2 + 7x + 11)
  • = 2[d/dx] x3 + 5 [d/dx] x2 + 7 [d/dx] x
  • = 2(3x2) + 5(2x) + 7(1) =
6x2 + 10x + 7
Find the derivative of y = x[1/3]
  • dy = [d/dx] x[1/3]
[1/3] x−[1/3]
Find the derivative of y = (x + 4)2
  • dy = [d/dx] (x + 4)2
  • = [d/dx] (x2 + 8x + 16)=
2x + 8
Find the derivative of y = √2 x2
  • dy = [d/dx] √2 x2
  • = √2 [d/dx] x2 =
2 √2 x
Find the derivative of y = 2 √x
  • dy = [d/dx]2 √x
  • = 2 [d/dx] √x
  • = 2 [d/dx] x[1/2]
  • = 2 [1/2] x−[1/2]
  • = x−[1/2] =
[1/(√x)]
Find the derivative of y = [(x3)/(x[1/3])]
  • dy = [d/dx] [(x3)/(x[1/3])]
  • = [d/dx] x3 x−[1/3]
  • = [d/dx] x(3 − [1/3])
  • = [d/dx] x[8/3]
[8/3] x[5/3]
Find the derivative of y = (√x + 1)2
  • dy = [d/dx] (√x + 1)2
  • = [d/dx] (x + 2√x + 1)
= 1 + x−[1/2]
Find the derivative of y = x − [(x3)/3!] + [(x5)/5!]
  • dy = [d/dx] (x − [(x3)/3!] + [(x5)/5!])
  • = 1 − [(3x2)/3!] + [(5x4)/5!]
1 − [(x2)/2!] + [(x4)/4!]
NOTE: y in this problem is a truncated version of the series representation of sin(x).
Find the derivative of y = 1 − [(x2)/2!] + [(x4)/4!] − [(x6)/6!]
  • dy = [d/dx] (1 − [(x2)/2!] + [(x4)/4!] − [(x6)/6!])
  • = 0 − [2x/2!] + [(4x3)/4!] − [(6x5)/6!]
−x + [(x3)/3!] − [(x5)/5!]
NOTE: y in this problem is a truncated version of the series representation of cos(x).
Find the derivative of y = 1 + x + [(x2)/2!] + [(x3)/3!] + [(x4)/4!]
  • dy = [d/dx] (1 + x + [(x2)/2!] + [(x3)/3!] + [(x4)/4!])
1 + x + [(x2)/2!] + [(x3)/3!]
NOTE: y in this problem is a truncated version of the series representation of ex.
