Exemple de sortie écran :

 The position vector of a moving point at time t is  

 r(t) = f(t)i + g(t)j + h(t)k 

 With 

 f : t-> 4*cos(t)  
 g : t-> 9*sin(t)  
 h : t-> t

   1 < t < 5 

 Find the tangential component of acceleration at time t. (aT)

 Find the normal     component of acceleration at time t. (aN)
