Re: cos(pi/2) n'est pas égal à 0 (mode Home)

Hi mrgx_cmte, in "Home" mode the value of PI is approximated to 12 digits so, typing PI is like typing 3.14159265359. Since 3.14159265359 ain't like PI, cos(PI/2) is not exactly 0. The CAS works symbolically while HOME environment is numerical, they yield different results. Have a pleasant...

Re: Problem with csolve

1+0.8x=0, multiplying both sides by 10 we get 10+8x=0 ;)
Now 8x=-10 and finally x=-5/4 :)
As Critor rightly said, there are no complex roots for given equation.
