For 3(c), I don't understand why the lowest value of theta wasn't just 33 from part b?

anyone help?

They changed the equation, the positive went to a minus.

For 5i what did people do with the sin and cos?

Also part 2a is wrong, -4x^2-20=-4(x^2+5) so -4/x^2+5

It looks like everyone's agreeing with OP on that one. That was a cruel question though, it looked like it should have cancelled down. Like someone further up I redid the entire question assuming I had made a mistake. The bastards did that intentionally.
