🎯 Key Summary of This Session This lecture thoroughly explains the concepts of left and right derivatives, which frequently appear in absolute value, interval functions, and graph problems on the CSAT Math exam, and applies them to actual past exam questions. In this 25th lecture, we will: ✔️ Define and differentiate left and right derivatives ✔️ Left and right derivatives in absolute value functions ✔️ Complete theorem of left and right derivative sum functions ✔️ Conceptually organize how to interpret left and right derivatives on graphs, and then directly apply them to problem #22 of the September 2022 KTEA exam, leading to a practical solution. The goal is not simple calculations, but rather a flow of concepts → conditional interpretation → practical application. 📘 [Watch the full series of "Ojal Kang Concepts"] 👉    • 수능 만점을 위한 꿀팁!! (오짤강)   🕔 What is Ojal Kang? This is a special lecture series that delivers essential CSAT math concepts and practical applications in "5 (5) minutes" (short and powerful). (※ In reality, it often exceeds 5 minutes 😊) 👉 If you're weak in left-right differentials, be sure to review them. 👉 Ultimately, students who understand the concepts are the ones who solve past CSAT questions. #CSATPerfectScore#CSATMath#PastQuestionExplanation#SeptemberMockTest#KoreaEvaluationInstitutePastQuestions#DifferentialCoefficients #Left-RightDifferentialCoefficients#Calculus#CSATConcepts#SimSangHoMath#OjalKang
