We need to subtract this thing evaluated at zero. So that's going to be negative e to the zero over four. Well that's just, e to the zero is one. So that's just negative one, negative one over four. And once again, all of this is going to be multiplied by 1 1.5. And now we just have to simplify it. So this is equal to, I'll just still throw out the 1 1.5 here.
