Basic Math Calculus – You can Understand Simple Calculus with just Basic Math!

I last took a math class more than 50 years ago, but enjoy problems in keeping a guy over 70 mentally active. Best wishes from Great Lakes Area, USA

It was a fun refresher for us old heads. Thank you, teacher.

Where were you when I was riding the struggle bus in college????? It took me forever to figure out what we were doing. Love this explanation.

I’m in the 40 years ago camp. Love these reviews. Haven’t had to show my work since. 😮 Please keep ‘em coming and thank you. Wish you were my teacher back then!

I took Calculas many years ago. There was one problem we did in class that involved: Given a certain volume - we had to come up with the dimensions of a circular can & I believe the can was open on one end for this particular problem. The idea was to develop the diameter & height of the can that used the least material. I thought it showed a good practical example of Calculas & I may have in my notes from 35 years ago. Anyway, I like your YouTube's

I minored in math when I was in college. It is sad that I forgot almost everything I had learned. These videos are great a refreshing my memory. Perhaps it is good for the brain.

Best introduction to Calculus. The right pace and very easy to follow.

I have never seen a better explanation of pre calculus until I saw this video. This guy's math students were very lucky to have him as their teacher

Great video! Always struggled (40 + years) but never lost curiosity. You are a good teacher.

I wish I had teachers that explained math like you!

I suffered through 2 years of calculus in college back in the 60's and never really knew what I was doing. If I had this prof instead of the ones I had back then, maybe I would have managed A's and B's instead of C's and D's. Then I wouldn't have had to give up my original major of Physics to major in something that didn't require Calc. BTW, I graduated as a Biology major.

You are very talented. I know many who teach fail to convey concepts well because they actually have a poor understanding of the concept themselves. Their students suffer and may actually fail through no fault of their own. They actually will lose their self esteem and blame themselves. Even instructors who do have a good grasp of the concept can have no ability to transfer their knowledge to their students. Again, the student blames themselves. I always said, that a good instructor can simplify the subject matter ,even if it is complex if they have the talent! YOU SIR, HAVE THE TALENT. THANK YOU.

Nicely done. Your teaching shows that you anticipate the puzzling aspects of math and do a good job at addressing them. I am NOT math talented, but my university advisor (and Chair of Chemistry) insisted I take calculus, differential equations and applied differential equations courses. The D.E. professor was French and spoke with such a strong accent I could scarcely understand him. The applied differential equations prof put it 😮all together because he was an engineer, not a math geek. The light bulb went on, and I realized WHY I was learning the stuff. However, after graduation I used NONE of it. 😅

Very well explained. Where were you when I was talking Calculus back in the 1960s? If Calculus were explained like this, my Engineering classes would have deeper understanding.

Failed hard in calculus in college, never understood it thereafter, and tried a couple of times, until today! Wow. I get it. Thanks!

Great episode. It's also a good way to help explain digital audio to my students in that an analog to digital converter breaks up the analog audio (the area under the curve) into narrow rectangles (the width determined by the sample rate and the accuracy of the height determined by the bit-depth). Thanks.

I last did this sort of calculus around 40 years ago. Differentials were predictable, but integrals were more like guess-work! But with my practical engineering approach I just imagined an area between 2 & 3, i.e. 1 unit wide, with a height starting at 2^2=4 and increasing to 3^3=9. So the answer 1 x (something between 4 & 9). Being a U shaped curve, the area is going to be around 5 or 6 (less than the halfway point between 4 & 9, which is (4+9)/2 = 13/2 = 6.5). Since you gave us a list of 4 choices, the only ones around that range are b)6 or d)19/3 (= ~6.333). I rejected it being a nice round integer like 6, so chose 19/3 - a little above 6 and closer to the 6.5 mark than I intuitively expected, but clearly the only 'sensible' answer 🙂. I loved most of maths at school, but I'm not sure most of it has been much use in 40 years of engineering and software development!

I like your channel but I find the length of the videos to be too large. Ten to twelve minutes should be enough. For example, if the viewer knows this simple integral then the only thing that remains is the subtraction of 27/3 - 8/3 in a jiffy. 23+ minutes is just way too wordy.

What I did was take the Stanford Quantum Mechanics class 101 online, providing a spin to the type of problem solving and math concepts that I was used to from engineering.

I did it in my head and I got 19/3. It was actually trickier than I thought as I had to hold so many intermediate values in my head. I think it’s right.
