Newton came up with the power series formula and it states that there are 180 degrees in a half circle. (Cause thats all the formula accounts for.) the power series cannot do 200 degrees thats why there is only 180 degrees. a new formula that can do 200 degrees would change the status quo. you guys ...

Richard you did it!!! You proved there are 100 units or degrees in a quater circle.!!!!!! Just divide pion2 by 100 and you get 100 perfectly spaced degrees. '' Albert's attempt at a 400 degree circle ... is the yellow line '' Richard's attempt at TwoPi radian circle ... is the pink line '' the refer...

I'm dialing it in slowly, 100 degrees per quarter. Its almost perfect. a little short around 80-90. '' Albert's attempt at a 400 degree circle dim as double deg,sine,cosine dim as double xctr,yctr,radius,x,y,holdx screen 19 xctr = 305 yctr = 305 radius = 300 circle(xctr,yctr),radius+1,9 x = radius y...

I made a new formula. Thinking there had to be 100 degfrees in a quarter circle. Its pretty close, some wide degrees low and high. The problem is it makes a squared circle. ???????? Got any input Richard? '' Albert's attempt at a 400 degree circle dim as double deg,sine,cosine dim as double xctr,yct...

there was a problem with the x center and ycenter in the above code. I corrected the xctr,yctr so now you can plot to any position on the screen. dim as double x,xctr,y,yctr,deg,offset,radius,size screen 19 xctr = 305 yctr = 305 radius = 300 offset = sqr(.5) size =(xctr + (offset*radius)) - (xctr - ...

Hey Richard!!! I tried and pretty much succeeded this time. I thought my formula made pretty good quarter circles. So! I tested it to see and got almost perfect circles. Almost perfect! dim as double x,xctr,y,yctr,deg,offset,radius,size screen 19 xctr = 305 yctr = 305 radius = 300 offset = sqr(.5) ...

Thanks Richard , i just looked at the formula and realized that i did a : ( / deg * deg ) thnigy which can be taken out. you can also get the same thing by pi / 180 / ( ( 90 / deg / 90 ) + ????? ) I'll try your formula. your formula returns the same results as mine! what i'm testing against is: ( pi...

my newest formula. the zoom is only set to 100 falls a little below around 30 degrees it only equals .499 instead of .5 not too bad for a single line formula! '--------------------------------------------------------- ' plot sine function and approximations '-----------------------------------------...

My newest formula is also a flop but its pretty close from 30-60 deg. ??? this code goes in to Richards sine plotter progam in this topic. 'albert's newest formula (thursday october 22 2009) ---- another failure, follows pretty close from 30 - 60 deg. dim as double value1,value2, value3,value4 for d...

So Richard with your cosine-plotter program i just enter my formula after yours at the bottom right???



Cool program! Thanls!

I didn't get the email on your above post. But i got 1000x in a second formula , a little better but more constants than i care to have in there. my lines is blue and the error green. I'll check out your above program to see what it is. '--------------------------------------------------------- ' pl...

Richard i set the zoom to max (=99999999999999999999999) and the true sin() function doesn't equal 1. ??? how can i dial my formula in???? my formula is 100% accurate at 0, 90 and 180 but i'm trying to dial it in and keep having to redo it every time i increment the zoom by 10 times. so i set it to ...

I found a way to make an upside down round cornered square.

y = .001 / ( ((180-deg)/45) * (deg/180) )

.001 makes it 4.5 tall. .01 makes it 45 tall.

it clips the waveform if you set the .001 to .2 it clips at .2

I got the formula refrased to: y = ((180-deg)/180) * (deg/180) * 4 Its still 3 degrees wide though. but the 4 is easier to remember than .0222222222222222222222222 maybe not though. but the *4 comes out to exactly 1 instead of .99999999....... Were back to the drawing board on formula creation. y = ...

Thanks Richard I enjoy your posts your a great mathematician your formulas have been somewhat helpful. I was wondering if you could modify your sine-plotter program to allow for huge amplification and scrolling the waveform around the screen with the arrow keys. I'm not sure but i think it could be ...
