Okay, Fund the power serious presentation from function and determined that interval of CA murders. So we're going to transform it into this woman. Tw note t equals for at square, and this is very familiar to us. So this is simply equal to the Siri's. And in this from zero to infinity. So what is planning this registration? And if one dies, it will be. And we know that he is less than one the absolute bellhop. Taste like the one soda, miss for square.
