**generate sine wave with microcontroller**

I want to design a digital signal generator which can generate digital values for the Sine wave using 8051 and then convert it to analog sine wave using DAC0808. But how to compute values for a function x[n] = sin(w n) using 8051 if i want 50 samples per cycle and 100 Hertz frequency of sine wave. I don't want to use lookup table in which i already have 50 values for 1 cycle of sine wave. I want to compute the values in realtime using 8051. Any DSP concepts which might be good for generating sin(w n) ????
