Finding Real Solutions of Quadratic Equations: Everything You Ever Need to Know patrickJMT 2022-08-29 | Here I show a few examples of finding real solutions to quadratic equations. If you know these techniques, there is really nothing else you ever really need to know. Either factor by trial and error, use factoring by grouping (I personally never use this one) or the quadratic formula. Boom: done.
Hypothesis Test : Performing a Full Hypothesis Test, Ex 1 patrickJMT 2024-04-29 | In this video, I show how to perform a one-tailed hypothesis test. In this video we discuss: formulating the null hypothesis and the alternative hypothesis, test statistic, one-tailed and two-tailed hypothesis testing, the central limit theorem, the decision rule, type 1 error, level of significance and more.This video would be suitable as a nearly full lecture in a statistics class with a few extra supplemental examples.

2.4 PreAlgebra Problem Solving and Word Problems patrickJMT 2024-04-16 | In this video we begin my looking at literal equations and discuss many examples of solving or isolating a variable. We look at other examples of applied linear equations involving question concerning simple interest, consecutive numbers, and consecutive odd numbers.We also examine how to take an (English) statement and translate it to the language of mathematics.This video is appropriate for any student taking a PreAlgebra course.
PreAlgebra 2.3 Combining Rules to Solve Equations patrickJMT 2024-04-15 | In this video, I do a combination of sections 2.1 and 2.2 to solve linear equations. Many more examples of solving linear equation are shown including equations involving fractions. For the equation involving fractions, we show how to get rid of fractions by multiplying both sides of the equation by the LCM of the denominators.After that, we discuss identities and contradictions, showing linear equations that have infinitely many solutions and no real solution.high school math, LCM, fraction, denominator, linear equation, solve, solving, tutorial, how to, help

Likewise we apply the same procedure to show how to divide like terms by subtracting exponents. Many examples of applying these two properties of exponents are shown. We also discuss what raising a nonzero variable to the power of zero produces numerically.I do not discuss negative or fractional exponents in this video.

Cylinders and Quadratic Surfaces Part 1 of 2 patrickJMT 2023-09-09 | Here we talk about the multivariable Calculus concepts of cylinders, traces, quadratic surfaces and classifying them.I show a couple of basic examples of graphing cylinders by hands, show the notion of traces and produce a rough graph followed by graphs from WolframAlpha.com (thanks Wolfram!) along with a few more graphs. The video ends with questions for you to practice that I will complete in part 2 of 2.Thanks to my supporters on Patreon: patreon.com/patrickjmt
Filling in Venn Diagrams with Numbers patrickJMT 2022-09-01 | In this video I work out multiple examples of filling in Venn Diagrams with numbers to represent and / or (intersection and union) of events.I use examples containing two sets (so two circles) and also three sets (three circles).
