qual é a derivada destas funcoes .Achar os pontos maximos e minimos.
 
f(x)=exp(x^3-x)
f'(x)=exp(x^3-x)*(3*x^2-1)
min=0 / min=0,68052  max=1,4697 max=[inf]
f(x) sobe de 0 a 1,4697, desce até 0,68052 e sobe ao infinito.
 
 
 
 
f(x)=x*sqr(x-x^2)     sqr=raiz quadrada
f'(x)=sqr(x-x^2) + x/[2*sqrt(x-x^2)]*(1-2*x)
min=0  max=0,32476
 
 
 
 
f(x)=(cos x )/(2+sen x)    
f'(x)=[ (-sen x)*(2+sen x ) - (cos x)^2 ] / (2+sen x )^2
min=-0,57735  max=+0,57735
