Congradulations!  You've just downloaded the most complete TI-83 programs
for Calculus that exists!

Instructions:  Send the group file to your TI 83.  It contains the programs:
conics
moments
torus
arclen

Program "torus" can find the definite integral of any function.  It also
can find the left rectangle, right rectangle, midpoint, trapezoidal and
Simpson's approximations within seconds!  It also will find the arclength\
of the function.

Program "conics" is for the section of calculus 2 that deals with conic sections 
(circles, ellipses, hyperbolas and parabolas).  Simply type in the coefficiants of the
equation (Ax^2+By^2+Dx+Ey+F=0), and it will identify the conic section and compute any info
you want from it(center, vertices, directrix...etc)!

THanx goes out to............me!  I made it, and I will take the credit!
Bwa ha ha ha!
