[SOLVED] "for" loops and "sin()"

[PEF524]

hey...

 

im trying to make a loop using all of the degrees 0-360 and displaying with the Sine of each of those is EX) 

Angle  Sin

  0      0

  1    .01745

  2    .0349

etc etc

 

... this is what im doing and it is not working, can anyone help?

 

<?php

$sin=sin($i);

$i=deg2rad($i);

for($i=0; $i<=360; $i=$i+1)

echo "$sin";

?>

 

thanks!

<?php
for($i=0; $i<=360; $i=$i+1)
   $d=deg2rad($i);
   $sin=sin($d);
   echo "$sin";
?>

You have some things backwards, try that?

ugh...

 

thanks but that didn't work for me

for whatever reason its not looping through all of the degrees

for the code you gave me it just said "-2.44921270764E-16"

I'll keep playing around with it

try starting at 1 instead of 0?

[PEF524]

still no luck, even with changing 0 to 1

i basically just want a list of all the sines of all the angles without having to write out the sin() function for each one...

 

anyone else have any ideas?  ???

What happens if you just do:

print sin(deg2rad(1));

Does that work?

 

The sin of 1 degree, is very small, right, it's almost 0, yeah? (or is that cos?)

So it should print a very small number. You may have to format it in order to get it to look right.

echo "<table><tr><td>Angle</td><td>Sin(x)</td></tr>";
for ($i=0;$i<=360;$i++) {
 $d = deg2rad($i);
 $sin = sin($d);
 echo "<tr><td>$i</td><td>$sin</td></tr>";
}
echo "</table>";
