    How to find the maximum velocity or accelreation?

    E.g v = v = 6t^2 + 3t -2 or a = v = 6t^2 + 3t -2 i know for velocity and acceleration, it is the derivitive equal to zero. but how do we prove that these points are a maximum? do we differentiate again, after already differentiating and sub values of t in? ++ Another...

    questions about displacement, velocity and acceleration curves

    there is no actual explanation in textbooks. However there is always at least one question on this. First of all if you are given a displacement curve: where is acceleration zero? where is velocity greatest? where is velocity lowest? when is acceleration greatest? and if you are given an...

    finding the maximum and minimum of trigonometry curves.

    i am having trouble with this concept in general because instead of differentiating to find dy/dx then equating to zero (then solving normally), the answer in the book draw the graph instead and look on the max and min points on there. Why do they do this? i.e this question. between 5am...
