Ol�, pessoal,
Estou com dificuldades para encontrar a solu��o do seguinte problema:
Considere
a curva de B�zier controlado por b0 = (0,0), b1 = (1,2), b2 = (3,3) e
b3 = (3,0), nesta ordem. Encontre o valor de t para o qual a derivada
da curva � paralela ao segmento &b1
obs.: &b1 = b2 - b1
Algu�m pode me dar uma luz?
Muito obrigado.
