Ignore this row, ignore this column. So plus k times cosine theta times r cosine theta is r cosine squared of theta. And then from that, I'm going to subtract negative r sine theta times sine theta. So that's going to be negative r sine squared theta, but I'm subtracting it. So it's going to be plus r sine squared theta.
