Presentation Transcript

  1. Eksponentielle funktioner - Redegør for hvordan man løser eksponentielle ligninger fx 3*1,3^x = 17.

  2. Disposition • Forskrift • Ligning – herunder tillægsspørgsmål • Halverings- og fordoblingskonstant • Eksempler fra NSpire

  3. Forskrift • a= • b= y0a-x0

  4. Ligning • Logaritmereglen ln(ax) = x*ln(a) • Tillægsspørgsmål: Redegør for hvordan man løser eksponentielle ligninger fx 3*1,3^x = 17.

  5. Halverings- og fordoblingskonstant • Fordobling: T2= ln2ln⁡(a) = ln2ln(1+r) • Halvering: T0,5= ln⁡(0,5)ln⁡(a) = ln⁡(0,5)ln(1+r • Hvad kan man med det?
