A pregnant woman is concerned about eating fish because of its potential contamination with mercury. What advice would you give her?She can substitute foods with a high omega-6 fatty acid content because it can be converted to healthy omega-3 fatty acids byenzymes.She can select fish species that provide EPA and DHA but are low in mercury content, such as salmon.She can substitute foods with a high omega-6 fatty acid content because it can be converted to healthy omega-3 fatty acids by enzymes.She can cook and process the fish to reduce its mercury content.Cashews are excellent sources of omega-3 fatty acids and can be used instead of fish.She can eat any fish and be guaranteed to receive the omega-3 benefit without the mercury risk.

1. Ecuación de calor 1.a Resuelve la siguiente EDP por el método de Variables Separables: $\frac{\partial^2 u}{\partial x^2} = \frac{\partial u}{\partial t}$, $0 < x < L$, $t > 0$ $u(0, t) = 0$, $u(L, t) = 0$, $t > 0$ $u(x, 0) = f(x)$, $0 < x < L$. 1.b Si $u(x, 0) = 100$, $L = Pi$ y $k = 1$; verifica que los coeficientes $A_n = \frac{2}{L} \int_0^L f(x) \sin(\frac{n\pi x}{L}) dx$. de la EDP anterior están dados por $A_n = \frac{200}{\pi} [\frac{1 - (-1)^n}{n}]$ y que su solución $u(x, t) = 2 \sum_{n=1}^\infty (\int_0^L f(x) \sin(\frac{n\pi x}{L}) dx) e^{-k(n^2\pi^2 t/L^2)} \sin(\frac{n\pi x}{L})$. está dada por la siguiente expresión: $u(x, t) = \frac{200}{\pi} \sum_{n=1}^\infty [\frac{1 - (-1)^n}{n}] e^{-n^2 t} \sin nx$.
