Some of the most commonly used functions:
y = mx + b
y = x**2 [x²]
y = x**3 [x³]
y = sqrt(x) [√x]
y = ln(x)
y = log(x)
y = sin(x)
y = cos(x)
y = tan(x)
Standard Operators:
+  addition and unary positive
  subtraction and negation
*  multiplication
/  division
!  factorial
**  pow, exponentiation
sqrt(x)  square root
cuberoot(x)  cubic root
Standard parameters (constant):
phi  returns the value of ϕ (the Golden Ratio). Also recognized as ϕ()
pi  returns the value of π. Also recognized as π()
pi_2  returns the value of π/2
pi_4  returns the value of π/4
tau  returns the value of τ. Also recognized as τ()
sqrt2  returns the value of the square root of 2
e  returns the value of e
log2e  returns the value of the log base 2 of e
log10e  returns the value of the log base 10 of e
ln2  returns the value of the log base e of 2
ln10  returns the value of the log base e of 10
Standard Functions that take 1 parameter:
sqrt()  returns the square root of the passed parameter
log()  returns the base 10 log of the passed parameter
ln()  returns the base e log of the passed parameter
log2()  returns the base 2 log of the passed parameter
ceil()  returns the passed parameter rounded up
floor()  returns the passed parameter rounded down
Trigonometric functions:
sin(), cos(), tan()
Their inverses (asin, acos, atan, atan2)
Their reciprocals (csc, sec, cotan)
The reciprocals of the inverses (acsc, asec, acotan)
The hyperbolic variations of all the above functions (sinh, cosh, tanh, asinh, acosh, atanh, csch, sech, cotanh, acsch, asech, acotanh)
The versine functions (versin, vercosin, coversin, covercosin, haversin, havercosin, hacoversin, hacovercosin, exsec, excsc, crd)
dtor()  converts the passed parameter from degrees to radians
rtod()  converts the passed parameter from radians to degrees
Quick Start:
1. Tap on [+] button.
2. Change the equation of the line to y=3x+1 and see graphed.
3. You can also enter equations that are not solved for x e.g. x=2y+2
About Graph Calculator
In mathematics, the graph of a function f is the set of ordered pairs (x,y), where f(x)=y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in twodimensional space and thus form a subset of this plane.
