User manual for graphing calculator

1. Type the function with variable x and y, then graph of the function will be drawn automatic.
2. You can change x-scale and y-scale in input boxes.
3. For algebraic function, you will use: abs(x) instead of |x|
sqrt(x) instead of sqaure root of x or x1/2, x^2 or x**2 instead of x2
log(x) instead of logx, ln(x) instead of lnx, e^x instead of ex
4. For trigonometric function, you will use in Radian angles and :
sin(x) instead of sinx, cos(x) instead of cosx
tan(x) instead of tanx,cosec(x) instead of cosecx
sec(x) instead of secx, cot(x) instead of cotx
5. For Inverse circular function, you will use in Radian angles and :
asin(x) instead of sin-1x, acos(x) instead of cos-1x
atan(x) instead of tan-1x, acosec(x) instead of cosec-1x
asec(x) instead of sec-1x, acot(x) instead of cot-1x
6. For hyperbolic function, you will use:
sinh(x) instead of sinhx, cosh(x) instead of coshx
tanh(x) instead of tanhx,cosech(x) instead of cosechx
sech(x) instead of sechx, coth(x) instead of cothx
7. For Inverse hyperbolic function, you will use:

asinh(x) instead of sinh-1x, acosh(x) instead of cosh-1x etc.

8. For implicit function, you will use two input boxes and equal sign(=) is situated between two input boxes..
Drawing the implicit function graph, it will take some times. May be 2 sec to 1 min. Hence, be pateince.
For some approxiamation error, the sketch will be thick but the shape will remain unchanged. sorry for that.
9. For Polar function, you will use two input boxes and equal sign(=) is situated between two input boxes. The input box of left side is function of r and the input box of right side is function of t
Drawing the polar function graph, it will take some times. May be 20 sec to 2 min. Hence, be pateince.
10. We can use maximum four functions and four conditions respectively for piecewise function. If you could not find < or > or <= or >= sign, then you can copy any where or here and past it.Type any mathematical function in the left input box , any valid condition in the right input box and then press the drawing button. It takes sometimes to draw graph of this function and be patience to calculate huge points to draw the graph. For zoom this graph, you can change the x-scale and y-scale. As for example of the interval or conditions, write 1<=x<=3 for [1,3] , x!=3 for x is not equal to 3
11. This is an online educational tools to make graph of mathematical linear programming or operation research of 2D in this section.Type any mathematical inequalities in the Five input boxes and then press the drawing button. For geting feasible area or region, press feasible Area or Feasible Region button
