Isoler une variable dans une formule 💥 Facile ! Je t'explique avec U=R×I et V=⅓ π r² h 💪 Brevet Bac

🎯 In this video, you'll learn how to isolate a variable in a formula! I'll explain step by step how to manipulate formulas to find an unknown variable, without getting lost in the calculations. 👉 We'll work with two important examples: • the electrical formula U = R × I • the formula for the volume of a cone V = 1/3 × π × r² × h You'll see: • how to identify the variable to isolate • which operations to use (×, ÷, +, −) • how to "do the inverse" to keep the equation true • simple tips to avoid common mistakes 🎯 Ideal for: middle and high school preparing for the Brevet or Baccalaureate exams better understanding formulas in physics and math 👍 Like if this helps! 🔔 Subscribe for more math explained simply! #IsolatingAVariable #Formula #Maths #Physics #National Exam #High School
