     This feature enables you to define the number
of decimal digits of calculations.  When the Accuracy
Window pops up for the first time the Accuracy is
defined as 16.  You can change the value from 3 up
to 16.

     Blowing up from "VIEW" Menu allows you to examine
the result closely.  Once you choose this option the
CROSS cursor appears then goto the left upmost point
and push the left mouse button.  Goto the right bottom
of the new scope and then Release the button.
#
     You can differentiate functions visually from 
Differentiate of "TASK". Also you can do it numerically
by choosing Differentiate from the Differentiate from
"Examine Numerical Results".  But when you differentiate
a function you must define H interval which is predefined
as "0.1".
#
     "Finding Roots" finds root by both Newton's method
or Bisection method.  The Newton's method here is
'Secant Method'.  Then you can trace the procedure of
finding roots by "Examine Numerical Results".
#
     Every function used by CALCULUS 1.01 is defined as

_______________F(X)=function of X_________________

You must use "X" to identify the unknown variable. Also
the function could be a Constant function.
#
     Calculus 1.0 uses infix form to communicate with
users.  It can analyze all the infix forms. One thing
users have to be careful about is CALCULUS doesn't put
multiplication operators between adjacent operands.  For
example if you input "2X".  Then you get Error Message
because calculus does not make 2X into 2* X.
#
    "Scoping" is similar to "Blowing Up".  But "Scoping"
gets input from the Key board. Therefore, with "Scoping"
you can see the result either closely or widely.
#
 CALCULUS 1.0 supports following functions.

Sin curve      -> "sin"      Cos curve         -> "cos"
Tan curve      -> "tan"      Exponential curve -> "exp"
Log of base 10 -> "log"      Natural Log       -> "ln"
Log of base 2  -> "lg"       Arc Sin curve     -> "asin"
Arc Cos curve  -> "acos"     Arc Tan curve     -> "atan"
