  • It's just unbelivable how easy you make these things to sound. I'm going to go back to university education soon and I really appreciate your work. English it's not my native language (it's Polish btw) but I live in the UK and I needed refresh of some basics in English. Why the other tutors don't teach like that? I also watching your College Calculus. Great Job Professor. Keep up good work.

    P.S. Complex number are not so complex anymore :)

  • How can one simplify this equation

    x = Sqr (Number) / Sqr (Number Feet/seconds ^ 2) its the feet per seconds squared that I can not seem to find out. It was a problem to see how fast a building will collapse.

  • This teacher is really outstanding he understands how to make it easier.

  • ok, But with an imaginary number, that says, we can allow contradictions with other number systems, are me now allowed to do i/0 ?

  • @FCCJStudent1 Yep! That's right. Cause 2's bigger than one. You have to remember twice as much- 2 instead of 1.

  • @polos505 Wait 'til you all find out it's all the same stuff!! He, he, he, he!! That's if you ever get that far!!

  • @Chutneybhai You're suspended until further notice!!! And you better not be late to class when you return!!!

  • @spott09 It means you're the sq root of neg. 1. You're imaginary man!!! You don't exist!!!

  • Gosh, this guy's an excellent teacher!!! Wish my college teaches were as good. I had some real, real, bad ones!!! Bad teachers really suck. They do more damage to the field than people realize!!! People think just because so & so get's A's & big degree he's qualified to teach- NO!!! He sucks!!! Watch out. He may have gotten A's & now professor but he may run more people away from the field than other teachers w/ lesser qualifications!!!! But this teacher is excellent.

  • @Dalianforever what the hell does that mean ?!!!!!!!!!
