Exemple de sortie écran :

 If 

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



 and f, g are differentiable, then

  r'(t) = f'(t)i + g'(t)j  



 If f, g are two time differentiable, then

  r''(t) = f''(t)i + g''(t)j

Exemple de sortie écran :

 Find r'(t) if  


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


 With 


 f : t-> 2*t    
 g : t-> 8 - 2*t**2  

 t = +6.00 


  r'(t) = +2.00i  -24.00j  



 Press return to continue.

Exemple de sortie écran :

 Find r''(t) if  


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


 With 


 f : t-> 2*t    
 g : t-> 8 - 2*t**2  

 t = +6.00 


  r''(t) = +0.00i  -4.00j
