Tue 14 Jan, 2014 12:23 pm - Yeah but does cosx = 0 and sinx = 0 not have infinite solutions?
I was at first using x = pi/2 or 3pi/2 but realised there would be more values
Sorry I know I'm probly being stupid , I... (view)
Mon 13 Jan, 2014 04:33 pm - I already tried this and but it did not show them, thanks
It is solving the two equations to get the points that I need help with, I have solved one for y then placed that back in but my... (view)
Mon 13 Jan, 2014 11:57 am - F(x,y) = (y^2+y-16)sin(x) find all stationary points classify them
I have found the derivatives and set to equal 0, now I'm stuck
F(x) = cos(x)(y^2+y-16) = 0
F(y) = sin(x)(2y+1) = 0... (view)
