My first assignment for calc III includes a problem where we try to match the two variable equations with their graphs without a calculator. i dont even know where to start. thank god Paul gave me some hints and he found this awesome free graphic calulator online that does SO MUCH cool stuff. i’d really recommend you to try it out even if you won’t take calc III in your life. 3d graphs are SOOO cool LOL
check out some screen shots. here are some of the equations i have to figure out in my first assignment. you can try to graph them =)
z = cos(sqrt(x^2+y^2))
z = sin y
z = -(1/(x^2+y^2))
z = cos x)^2*(cos y)^2
z = sin (x^2+y^2) / (x^2+y^2)
z = cos(xy)
z = abs(x) * abs(y)

We had to do that in Honors Calc, although not with such difficult equations!
*gags* that looks fun. i don’t think i’ve ever had to solve/graph an equation involving the variable “z” – but then again, I never took Calculus!
*feels dumb* in algebra II i’m memorizing properties.
