Definite Integrals with Unknown Limits | WASSCE Elective Math

Sometimes calculus is just algebra wearing a fancy hat. 🎩 In this tutorial, we are taking a WASSCE-style definite integral and breaking it down step-by-step. But here is the catch: we aren't just finding an area. We are hunting for an unknown upper limit, m. We will walk through the integration, but more importantly, we'll look at how to cleanly handle the messy fractions and solve the cubic equation that pops out at the end using the Rational Root Theorem. No guessing, just solid logic. Grab your pen and let's work through this one together. Think. Find. Shine. ✨ #Road2WASSCE2026 #WASSCE #ElectiveMath #FindXYZ #Calculus
