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.

To enter f of g equations in a graphing calculator, first define the functions f(x) and g(x) in the function editor. For example, if f(x) = x² and g(x) = 2x + 1, you would input these functions into separate slots. Then, to find f(g(x)), substitute g(x) into f, which can be done by entering f(g(x)) directly in the calculator, using the appropriate syntax. Finally, graph the resulting function to visualize the composition.
Using the Sine function Sin(x) = 0.5 Then x = Sin^(-1)0.5 x = 30 degrees. Sin^(-1) in the inverse function on you calculator. . It works for Sin , Cosine and Tangent of any angle.
(x,y) (-x,-y)
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
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] [±] [=]
