input as "Genneral Calculation"

NEED NOTE:
Genneral  Handwriting:

3X+4  [in zognc ERROR]
3*X+4 [in zognc Correct]
-3*X+4 [in zognc ERROR] 
f3*X+4  [in zognc Correct]

X just is Digital number
 
sinX X is angle , no pi (Radian), sin(X/180*pi)  is Radian 

a is Xrange,Closed interval [-a,a], Default a=12 ,a Don't  Negative
b is Yrange,Closed interval [-b,b], Default b=9 ,b Don't  Negative
c is Trange,Closed interval [-c,c], Default c=180 ,c Don't  Negative
c is angle, using "cos sin tan",or Genneral Variable to using

press "=" to draw 
press "C" to break,or clear

========================================
curve  y=[x]

input 

[x],a,b    or   [x]

using ","  Interval ,no "a,b" will using Default
========================================
conic y^2=[x]

input 
[x],a,b    or   [x]

using ","  Interval ,no "a,b" will using Default

if  "Y^2=x^2+y+3" ,using  "conic X=[t] Y=[t]"
========================================
conic  y^2 Known Root: X=[t] Y=[t]
 
X=[T],Y=[T],A,B,T

input 
[t],[t],a,b,t   or   [t],[t]

using ","  Interval ,no "a,b,t" will using Default
========================================
Example: 
circle is conic.
can using: input

Y^2 9-x^2
Known Root XY 3*cosT,3*sinT

Two methods to DRAW
