Mathjax数学公式

$$\int_{x^2 + y^2 \leq R^2} f(x,y),dx,dy = \int_{\theta=0}^{2\pi} \int_{r=0}^R f(r\cos\theta,r\sin\theta) r,dr,d\theta$$

English

At the Penfield mood organ, Iran Deckard sat with her right index finger touching the numbered dial. But she did not dial; she felt too listless and ill to want anything: a burden which closed off the future and any possibilities which it might once have contained. If Rick were here, she thought, he’d get me to dial 3 and that way I’d find myself wanting to dial something important, ebullient joy or if not that then possibly an 888, the desire to watch TV no matter what’s on it. I wonder what is on it, she thought. And then she wondered again where Rick had gone. He may be coming back and on the other hand he may not be, she said to herself, and felt her bones within her shrink with age.
