The AllAroundMathGuy's channel -- the place where you see how math can be found and applied all around you in everyday life! My goal is not only to help you truly understand math concepts, but more importantly to teach you to think mathematically about the world around you, and help you appreciate real-life applications of mathematics! Check out the latest situational math videos based in real-world contexts... you never know where I might be or what I might be doing! You'll also find Math & Calculus lesson videos, as well as past live classroom lecture screencasts. New videos are uploaded regularly, so check back often! The AllAroundMathGuy is Eric Balzarini, a teacher in Langley, BC, Canada.
Sorry I missed this when you asked. The algebraic expression for the two pieces is the piecewise function -- one part that has the exact equation that is given, and the the other part that is the opposite, ie. the negative of what is given. To determine where each part occurs, you need the x-intercepts as found in the video. You could test a point in each interval to see where the original function is positive or negative, and then 'flip' the parts that are negative with a negative sign in front.
Back when I made these videos I was using Microsoft OneNote - you can have it show a grid and set it to snap to the grid. The calculator is a virtual TI83+. You can find it at www.ticalc.org/archives/files/fileinfo/84/8442.html
Sorry you didn't find this useful or helpful - just documenting the process for converting the bike after some asked about it after the previous gear analysis video I made about this bike. And for anyone that doesn't like the music, there's always the mute button! 😉
Just had tuff shed build a shed and having this problem. Now I am having to go back and forth and I paid over $9000 for this shed. They saying that it is dating where I ask them to put it, but not addressing the building base is not squared is the reasons it is sating at an angle and not centered.🥴🥴
It’s 2024 and this video is 12 years old and STILL helping folks! I’m building a greenhouse base and this explanation of how to make a perfect rectangle is exactly what I needed. Thank you 😃
This is not cheating, haha, but when finding the reference angle you ignore the negative sign; then you reconsider the negative when deciding which quadrants the solution angles terminate in.
This doesn't help...which angle do i look at it from then? if theta is not showing up on my hw . I still am left confused to find which side is the opposite one
The opposite and adjacent sides depend on which angle you're looking at the triangle from - opposite is across from it and adjacent is one of the two sides that make up the angle. The hypotenuse, however, is always the longest side regardless of which of the two acute angles you're looking from.
