(2t^2)/3 = 8/3 pi^2

解答

\frac{2 t ^{2}}{3} = \frac{8}{3} π^{2}

解答

t = 2 π, t = - 2 π

+1

十进制

t = 6.28318 \dots, t = - 6.28318 \dots

求解步骤

\frac{2 t ^{2}}{3} = \frac{8}{3} π^{2}

分式相乘:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

\frac{2 t ^{2}}{3} = \frac{8 π ^{2}}{3}

在两边乘以

3

2 t^{2} = 8 π^{2}

两边除以

2

t^{2} = 4 π^{2}

对于

x^{2} = f (a)

解为

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

t = 4 π^{2}, t = - 4 π^{2}

4 π^{2} = 2 π

- 4 π^{2} = - 2 π

t = 2 π, t = - 2 π
