(-3/4)^2+y^2=1

解答

(- \frac{3}{4})^{2} + y^{2} = 1

解答

y = \frac{7}{4}, y = - \frac{7}{4}

+1

十进制

y = 0.66143 \dots, y = - 0.66143 \dots

求解步骤

(- \frac{3}{4})^{2} + y^{2} = 1

展开

(- \frac{3}{4})^{2} + y^{2} : \frac{9}{16} + y^{2}

\frac{9}{16} + y^{2} = 1

将

\frac{9}{16}

到右边

y^{2} = 1 - \frac{9}{16}

化简

1 - \frac{9}{16} : \frac{7}{16}

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

y = \frac{7}{16}, y = - \frac{7}{16}

\frac{7}{16} = \frac{7}{4}

- \frac{7}{16} = - \frac{7}{4}

y = \frac{7}{4}, y = - \frac{7}{4}

- 3 x^{2} - 7 x + 2 = 6

0 = 4 x^{2} - 8 x - 5

solvefor D,D^2y-Dy-6y=e^{2x}

so l v e f or D, D^{2} y - Dy - 6 y = e^{2 x}

solvefor x,3x^2+4y^2-6x-24y+39=0

so l v e f or x, 3 x^{2} + 4 y^{2} - 6 x - 24 y + 39 = 0

solvefor x,x^2+2x+y^2-6y=c

so l v e f or x, x^{2} + 2 x + y^{2} - 6 y = c
