Find the Domain of ln(x+2) | Precalculus Exercises @WrathofMath

Wrath of Math | Find the Domain of ln(x+2) | Precalculus Exercises @WrathofMath | Uploaded 2 months ago | Updated 9 hours ago
We find the domain of ln(x+2) by recognizing the argument of the ln function has to be positive for the natural log to be defined. That is, x+2 must be greater than 0. As a result we'll find the domain is all x that are greater than -2. We write the domain using an inequality, write the domain in interval notation, and then graph the domain on a number line. We conclude by looking at graphs of y=lnx and y=ln(x+2). #precalculus

$Integral of x/(x+1) | Calculus 1 Exercises We integrate x/(x+1) with u-substitution and without u-substitution. We can use a simple trick to split up the fraction without using the change of variable method because although the numerator isnt a multiple of the derivative of the denominator, it is only a constant off from the denominator. #calculus1 #apcalculus Join Wrath of Math to get exclusive videos, music, and more: https://www.youtube.com/channel/UCyEKvaxi8mt9FMc62MHcliw/join Calculus 1 Exercises playlist: https://www.youtube.com/playlist?list=PLztBpqftvzxUEqGGgvL3EuIQUNcAdmVhx Calculus 1 playlist: https://www.youtube.com/playlist?list=PLztBpqftvzxWVDpl8oaz_Co6CW50KtGJy ◉Textbooks I Like◉ Graph Theory: https://amzn.to/3JHQtZj Real Analysis: https://amzn.to/3CMdgjI Abstract Algebra: https://amzn.to/3IjoZaO Linear Algebra: https://amzn.to/43xAWEz Calculus: https://amzn.to/3PieD1M Proofs and Set Theory: https://amzn.to/367VBXP (available for free online) Statistics: https://amzn.to/3tsaEER Discrete Math: https://amzn.to/3qfhoUn Number Theory: https://amzn.to/3JqpOQd ★DONATE★ ◆ Support Wrath of Math on Patreon for early access to new videos and other exclusive benefits: https://www.patreon.com/join/wrathofmathlessons ◆ Donate on PayPal: https://www.paypal.me/wrathofmath Thanks to Loke Tan, Raül Beienheimer, Matt Venia, Micheline, Doug Walker, Odd Hultberg, Marc, Shlome Ashkenazi, Barbora Sharrock, Mohamad Nossier, Rolf Waefler, Shadow Master, and James Mead for their generous support on Patreon!

Isomorphic Vector Spaces and Isomorphisms | Linear Algebra

$algebra students, if you screw this up your teacher deserves to be mad Discussing a handful of tricky fractions which have a way of tripping up beginning students. These include 1/1, 0/1, 0/0, and 0/1. We discuss fractions and division in some depth to address these values and lackthereofs. You must understand the nature of dividing by 0. #maths #mathematics Join Wrath of Math to get exclusive videos, lecture notes, and more: https://www.youtube.com/channel/UCyEKvaxi8mt9FMc62MHcliw/join Math Chats: https://www.youtube.com/playlist?list=PLztBpqftvzxXQDmPmSOwXSU9vOHgty1RO Pallet Town Remastered: https://www.youtube.com/watch?v=2BQsxO-wUa4 Textbooks I like!
