evaluate the equation above for $x = 1.5$

Explanation:

Step1: Calcular (e^{x}) y (e^{-x})

Sustituir (x = 1.5). (e^{1.5}\approx4.4817), (e^{-1.5}=\frac{1}{e^{1.5}}\approx\frac{1}{4.4817}\approx0.2231)

Step2: Calcular la expresión (\frac{e^{x}-e^{-x}}{2})

Sustituir los valores de (e^{x}) y (e^{-x}): (\frac{4.4817 - 0.2231}{2}=\frac{4.2586}{2}=2.1293\approx2.13)

Answer:

2.13
