extreme s(t)=-4.9t^2+29t+2

解答

极值点

s (t) = - 4.9 t^{2} + 29 t + 2

解答

极大值 (\frac{145}{49}, 44.90816 \dots)

求解步骤

f^{'} (t) = - 9.8 t + 29

Find intervals:

递增

: - \infty < t < \frac{145}{49},

递减

: \frac{145}{49} < t < \infty

将

t = \frac{145}{49}

代入

- 4.9 t^{2} + 29 t + 2 : 44.90816 \dots

极大值 (\frac{145}{49}, 44.90816 \dots)
