maths doubts
astarmathsandphysics:
I have been thinking seriously about this since yesterday. I don't seriously think they can expect you to find all three roots of a cubic polynomial using the Newton Raphson method. You dont even know how many roots there are. The very first thing you would have to do would be to sketch the curve and see if you can find interval in which each root lies. Can you scan in the page with the question? I think there is something missing.

if u use Fx-991Ms
do this,..
On-->3 times "mode"--> "1" (Eqn) --> press the "right arrow" --> "3" --> type th co-efficient of x3 nd press "=" -->
type th co-efficient of x2 nd press "=" --> type the co-efficient of x nd press "=" --> type the value of "d" i.e co-efficient of x0 and press "=".
U'll get an answer..press "=" 2 more times to find the other values
e.g -> a cubic equation --> ax3 + bx2 + cx + d

hey..ssup..actually u can solve matrices and simultaneous equations too in Fx-991 MS.
and yea..my papers are going good..2morrow again a holiday followed by english paper 3!
