If you mean 1/x (some symbols get lost in the questions), that is called the reciprocal. It means, for any given number, find a number which, when multiplied with the given number, gives 1. Or equivalently, simply one divided by the given number.
y=x+1
5tanx=1 turns into tanx=1/5 then you use a calculator use the calculator function tan^(-1) this function should be the 2nd function of tan then in the parenthesis that come up type in 1/5 you should get .1974 therefore tanx=1/5 => x=.1974
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
If your calculator has an exponentiation function, simply raise the number to the power of .5 Remember this trick: the nth root of X = X ^ (1/n)
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
y=x+1
a four function calculator = x - + / if you have google you have this :)
Yes.

(x,y) (-x,-y)

f(f(x)) = f(x). Only if f is 1-1 then we have a solution f(x)=x.
sec x = 1/cos x → sec³ x = 1/cos³ x or sec³ x = (cos x)^-3 Therefore to enter sec³ x on a calculator: Newer, "natural" calculators: mathio: sec³ x → [x-power] [cos] [<angle>] [)] [navigate →] [(-)] [3] [=] lineio: sec³ x → [(] [cos] [)] [)] [x-power] [(-)] [3] [)] [=] Older, function acts on displayed number calculators: sec³ x → [angle] [cos] [x-power] [3] [±] [=]
