距离 (-4,-2),(-5,-6)

解答

距离

(- 4, - 2), (- 5, - 6)

17

求解步骤

计算

(x_{1}, y_{1}), (x_{2}, y_{2})

之间的距离:

(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

(- 4, - 2)

与

(- 5, - 6)

之间的距离是

= (- 5 - (- 4))^{2} + (- 6 - (- 2))^{2}

化简

= 17

s (t) = \frac{4 t}{sin ( t )}

f (x) = 7 x + 5

(x^{2} - 4)^{2}

f (x) = (- \frac{8 π}{11})

f (x) = e^{3 x} + e^{- 3 x}
