so i just needed to restrict that plane to a set of values that lie in both planes. so I am just wondering what exactly did i do by setting the two planes equal to each other? i notice i get the same result if i subtract equation 1 from equation 2, so did i just subtract the two planes by...
Ah i do notice that, but
x+2y+3z=4x+5y+6z-5
if i plug them into that those points solve the equation, which is the x,y,z such that those two planes are equal, or is that me failing at winging a problem?
My course is supposed to go from basic vector algebra to extrema, curl and divergence, (stopping before multiple integration)
I don't need any help on this assignment I am just wondering how hard it looks compared to everything else.
