equal to theta to D seven times I should have plotted it wrong it's like gonna go like this here theta to the seven times one minus theta we can bring up front and then there is left eight one minus theta plus 2 times theta equal to zero so we see that this thing will be equal to zero when theta is equal to 0 theta equal to 1 so those are actually minima rather than Maxima they're bad places to be but they have a derivative that's 0 and then the other thing is whenever this ting is equal to 0 which is 8 minus 8 theta plus 2 theta equal to
