Hi ayeshawzd
You can define the values of some basic logs like log2=0.3010 ,
log3 =0.4771 , log5 ,log7,log10. and so on
Then use these to find the other log values.
Like , log20=log(4*5) = log4+log5 = 2log2 + log5 ......

Hope it helps..........

Look up the series formula for the logarithm function and do the same as I showed you in the cosine thread.
