Miaow !

Testez ça : 1.5sqrt((-abs(abs(x)-1))*abs(3-abs(x))/((abs(x)-1)*(3-abs(x))))*(1+abs(abs(x)-3)/(abs(x)-3))*sqrt(1-(x/7)^2)+(4.5+0.75*(abs(x-0.5)+abs(x+0.5))-2.75*(abs(x-0.75)+abs(x+0.75)))*(1+abs(1-abs(x))/(1-abs(x))), (-3)*sqrt(1-(x/7)^2)*sqrt(abs(abs(x)-4)/(abs(x)-4)), abs(x/2)-0.0913722*x^2-3+sqrt(1-(abs(abs(x)-2)-1)^2), (2.71052+1.5-0.5*abs(x)-1.35526*sqrt(4-(abs(x)-1)^2))sqrt(abs(abs(x)-1)/(abs(x)-1))

sqrt(cos(1.8x))*cos(78 x)+sqrt(abs(x))-0.5),from -2 to 2

sqrt(cos(2x))*cos(99 x)+sqrt(abs(x))-0.7),from -2 to 2

Aaaaaanh, pleins de votes negs :\'(
