solve find the coefficient of x^5 in (5+8x^2)(3-1/2x)^6
2×4
three day diatary recall
x = x^2 - y^2 -1
y = 2y
x = x^2 + y^2 -1
x^2+y^2-1
2y
5x+4y=-83
3x+3y=-12
35*9
L+V=20
(X*L)+(Y*V)=10
Y=179.49*X/562
(1-Y)=1231.42*(1-X)/562
aproximar por serie de fourier la funcion f(x)=2x^2+2 en el interbalo (-2;2)
