    Hi all! Please post comments, questions and anything else on your mind in the comment section! While I try to answer as many questions as I can, there are more questions than I can answer by myself so if you are someone who might be able to help, please do so! The community is so much better when everyone is involved and helping each other out. Our strength is our willingness to help each other!
    Also please feel free to like or dislike the video. Your feedback is always appreciated so that hopefully I can make my future videos the best possible! Thanks and happy studies!

    You spent 12 minutes, and you taught me more than what my teacher could teach me in a semester, and for that thank you.

    Great help!! I just started engineering school 10 years after graduating high school. Needed a refresher and your videos are great!! Thanks! Keep up the good work!!

    We watch these vids as our Calc notes, and then do the homework in class. :) Absolutely LOVE it! These are soooo easy to understand, and then when we do the work in class with the teacher there, I know what is going on, and I know what I need help on and need to ask about. :) Thanks soooo much for making these videos! Our entire Calculus class really appreciates them! :)

    @patrickjmt  13 ปีที่แล้ว

    @chloetan2912 you are using set notation, i think i use interval notation. it is all the same thing, perhaps just ask your teacher if they have a preferred notation for you to use.

    @tasatful well, hosting videos is expensive. google/youtube is not going to do that for free. you can always find a subscription based service with no ads and pay to not see them.

    Thank you. From a 33yo returning to college.....and I had the fantastic idea to go for Engineering/Applied Mathematics. All help, especially good help, is GREATLY appreciated.

  • @patrickjmt
    @patrickjmt  14 ปีที่แล้ว

    @genemalu well, to draw a pretty accurate graph you can use calculus. otherwise, u just gotta plot some points and/or think about the function!

  • @liittlsky
    @liittlsky 12 ปีที่แล้ว +1

    I just wanted to say thank you so much for your videos! I am taking an online math course and have spent hours studying and reviewing my book and notes and was still having trouble understanding the information! But I watch your videos and it makes perfect since!

    WoW... i came for your help last year in my calculus class and now i am back here for my engineering basic calculus. THANK YOU

  • @patrickjmt
    @patrickjmt  13 ปีที่แล้ว

    @staacyum well, you have to ask yourself: what restrictions are there for a cube root? can i cube root any number? (yes, you can). so here the only problem would be having zero, since it would be in the denominator.

  • @TheCutedark
    @TheCutedark 12 ปีที่แล้ว

    Hello Patric..I'm a fan of Maths and I can't decribe how happy I am that I found ur videos. I just want to say that at minute 3:45 u can slove it with this formula: a*x^2+b*x+c=0 sloves x1/2={-b +- (b^2-4*a*c)^1/2} / (2*a) ..in our case is x1/2={-(-1) +-(1^2-4*1*(-6))^1/2} / 2*1 x1/2=(1+-5)/2 x1=(1+5)/2=6/2=3 and x2=(1-5)/2=-4/2=-2
    I don't know if u knew it but with this formula u can slove every quadratic equation.

  • @sarahholland5980
    @sarahholland5980 8 ปีที่แล้ว +8

    Thank you so much! My teacher skipped over half the rules (ex: when to use greater than or equal to zero vs. just greater than) and I was so incredibly confused. I have a quiz tomorrow, but you're a lifesaver! I'm subscribing and will look at some of your other videos for reference! :)

    the range of the f(x) is the domain of the inverse function.
    so find the range of the original

  • @patrickjmt
    @patrickjmt  13 ปีที่แล้ว

    @TheNorthfaceskater well it just depends on where the absolute value is and what the function is

    @darkhorse1723 well, then there are no radicals and no fractions, so there is nothing to worry about; ie, the domain is all real numbers

  • @enjoyablesounds
    @enjoyablesounds 14 ปีที่แล้ว

    Great video...I have a feeling, as time goes on, my list of questions, uncertainties will grow larger and my frustration only deeper, therefore I seek help.
    My first point is domain notation. For instance the following -1 < r < 1 Here "r" can sit in between -1 and 1, where these two number are not included, if I'm not mistaken. However if you would read this from left to right (usually the way the majority of people read sentences) you would read " -1 is smaller than r and r is smaller then 1"
