If needed to be calculated:

1) f(x)=x^(n)
2) f(x)=sin(x)
3) f(x)=cos(x)
4) f(x)=tan(x)
5) f(x)=arcsin(x)
6) f(x)=arccos(x)
7) f(x)=arctan(x)
8) f(x)=|x|
9) f(x)=e^(x)

Then enter:

f(x)=pow(x,n)
f(x)=sin(x)
f(x)=cos(x)
f(x)=tan(x)
f(x)=arcs(x)
f(x)=arcc(x)
f(x)=arct(x)
f(x)=abs(x)
f(x)=exp(x)

If needed to be calculated:

10) f(x)=ln(x)
11) f(x)=sqrt(x)
12) f(x)=[|x|]
13) e=2.7182818184...
14) π=3.1415926535...

Then enter:

f(x)=ln(x)
f(x)=sqrt(x)
f(x)=gint(x)
e
pi
