You can draw graphs by giving arbitrary values to a , b,...  Browser for Java is necessary. 

Type of y=f(x)

1. y=ax+b

2. y=a(x-b)

3. y=ax2+bx+c

4. y=a(x-b)(x-c)

5. y=a(x-p)2+q

6. y=ax3+bx2+cx+d

7. y=a(x-b)(x2+cx+d)

8. y=a(x-b)(x-c)(x-d)

9. y=ax4+bx3+cx2+dx+e

10. y=a(x-b)(x3+cx2+dx+e)

11. y=a(x-b)(x-c)(x2+dx+e)

12. y=a(x-b)(x-c)(x-d)(x-e)

13. y=a(x2+bx+c)(x2+dx+d)



Trigonometric functions

1. y=asin(bx+c)+d

2. y=acos(bx+c)+d

3. y=atan(bx+c)+d

4. y=acot(bx+c)+d

5. y=asec(bx+c)+d

6. y=acosec(bx+c)+d



Exponential function

y=a(bx+c)+d



Logarithmic function

y=bloga(cx+d)


Type of x=f(t), y=g(t)

1. x=acos(bt), y=csin(dt)



Type of f(x,y)=0


Calculation form of statistics

1. Basic statistics



Probability(density) functions, calculation forms for statistical analyses, etc. will be added.
