## Calculus – How to find the derivative of a function using the power rule

This video shows how to find the derivative of a function using the power rule. Remember that this rule only works on functions of the form x^n where n is not equal to zero. For more videos please visit http://www.mysecretmathtutor.com

I am new to this, so I have a question. Does it have to be simplified before finding the derivative? I am asking this because if you take y=x^2, you will get a derivative of y=2x, but if you take it from y=x*x, you will get y=1*1, so you will get y=1, which is different from y=2x.

what if the function was something like -2x+5

That's so easy

im in precalc and the way this was explained was about 10 times clearer than my teacher, thanks man

Nice explanation sir👌

The first one, f(x)=x^5…. I have the same in my textbook and it says the answer is f'(x)=3x^2

i wish you were my professor. I hope i do good in my business calc exam tomorrow

Very helpful. Thanks.

Big test tomorrow. Thanks

Very clear ,thanks man

Not sure why you are saying it doesn't work for 0? It does – equivalent to the derivative of a constant is 0.

my friend Drew recommended this video to me. Good guy, a little weird though…

these random math channels online are way better online teachers at any of the 4 online schools I've attended in the past year

How do you find the deriative of f(x) = (-2x+3)/(x^3-3x^2)? I would look up a video for it but I don't know what it is called. all videos I find are given either simple direvative tutorials like this one or very complex ones that are not the ones Im looking for.

Thank you!!

You are God man

Wow I really just absorbed all of this unit in 15 minutes…

I was an ace student in my math courses up until MA 241 (level 1 calculus) in my first year of college. I’d been struggling to understand a single damn thing from my Calculus textbook or any of the lectures we had, and was convinced math and physics was not my future after all.

Thank you so much. It’s time to turn this grade around!

legend, ty so much

Best maths tutor I have ever seen u have cleared my several doubts thank you

What if the exponent has a variable next to it? Do I still subtract it by 1?

This maths teacher is a guru/expert

I mean he explained in the simplest way I'll surely recommend your channel to my friends. Thank you

Thank you it was helpful It was very good

life saver!

what mic do you use? sounds good

sir i am In Love with u

gratzieee

Thank you for such an easy lesson, I was scared and never ever thought of learning about all this because of the fear. 😍😍

this is soo boring

you are the freaking best!!!!!!

Does the rule still function the same even if it is a symbol? So something like X(T)=T^2π

actual god
