Math videos from University of Texas math professor Lorenzo Sadun. The calculus videos mostly cover topics from integral and multivariable calculus, although there are a few from differential calculus, too. The linear algebra videos follow my book "Applied Linear Algebra: The Decoupling Principle" and are used for M346: Applied Linear Algebra at UT Austin.

    why do the antiderivative formulas look like integration formulas ???

    1:46 Why are you dividing the coefficients by factorials at this stage? 2:55 And again here, how are you even getting these fractional coefficients?

    In engineering (chemical) I use accumulation functions to generate a function which represents rate at which energy is flowing through a differential area. This is known as heat flux [=] W*m^-2 *s^-1. Instead, now I know why we DON'T express the integrand OR the differential volume in terms of the spatial variable (x (cartesian), r(spherical or cylindrical). It's because we're expressing a "running total" of heat flux (3:23), therefore we cannot use the spatial variable (x,r) in the integrand. rather we integrate up to the spatial variable (upper bound). I wish my professor was able to justify the mathmatical reasoning behind this like you do. It's more than just "using a dummy variable".

    What i am about to say applies to 90 percent of people teaching MATHS ! This explanations are not good enough ! only 3 /10 students will understand you ! because there are alot of gaps in your explanations ...... YOU SHOULD COMMUNICATE BETTER and aim to make sure that 8/10 students understand you ! Dont be lazy and assume that people learning are interested or have prerequisite knowledge make the effort to explain and point out the GOTCHAS . Such as : THETA is a freaking GREEK variable that you are using to represent an angle PHI is another freaking GREEK variable that you are using to represent another angle so theta and phi are variables just like a , b and c You didnt explain what is COS , SINE and tangent what are those !. You didnt make it obvious that SINE THETA + COS THETA =1 aka hypotenuse = opposite/adjacent Further more even before teaching all the above you should have taught them ABOUT the circle ALL the parts of the circle Theres more to it than just radias , diameter and circumference . I AM FURIOUS MAD that maths teachers are so lazy and not communicating stuff without GAPS ........ thus only 3/10 students can fill in the GAPS and the REST depend on cramming formulas without knowing WTH and why they are doing this calculations !!!!!!!

    That really nice explaining! ; but what if the function of the second example was not linear? And just a curve? Can you create two areas to sum or substrace them to find the integral?

    Here's some code for finding sqrt(5) with an initial guess of 2 in 4 steps. You can adjust as needed for other problems: N=4; % The number of steps a=5; % The number we're taking the square root of x(j)=2; %The initial guess for j = 1: N x(j+1) = (x(j) + a/x(j))/2; end; x % Print out the array of successive guesses.
