Beliebt Geometry >

T(n)=T(n-1)+n^2

Lösung

T (n) = T (n - 1) + n^{2}

Lösung

(h, k) = (0, 0), p = \frac{1}{4}

Schritte zur Lösung

T n = T (n - 1) + n^{2}

Rewrite

T n - T (n - 1) - n^{2} = 0

in the standard form

4 \cdot \frac{1}{4} (T - 0) = (n - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, 0), p = \frac{1}{4}

2y=-4*(x+2)^2+m+5

2 y = - 4 \cdot (x + 2)^{2} + m + 5

g(x)=-1/2 x^2-2

g (x) = - \frac{1}{2} x^{2} - 2

solvefor x,x=(t(x)+2)^2+5

so l v e f or x, x = (t (x) + 2)^{2} + 5

2 x^{2} + 3 x + 5 y = 0

x = \frac{T ^{2} - 2 T}{8}
