Despite the treatments you see in many sources, they are NOT, unless you are converting and exponential measurement into a Log. Transposing degrees Celsius to degrees F is often used as an example, but that is a misuse of the term "inverse", which is actually a cancellation of a function. A good example of an inverse function is the Log function X=10Y, the inverse of Y=10X.
A common function transposed to the other variable is a reversal, transpose, or converse. Many object to "converse", since that usually means "if p = q, then q = p"; but that's what a transposed equation is. Teachers will give you a hard time on the converse-inverse issue, since it has infected many textbooks. Go the the Mathematica site, or a good college precalculus book. See related link.

Division by a number is the inverse operation to multiplication by the number (and vice versa).

Apex: false A logarithmic function is not the same as an exponential function, but they are closely related. Logarithmic functions are the inverses of their respective exponential functions. For the function y=ln(x), its inverse is x=ey For the function y=log3(x), its inverse is x=3y For the function y=4x, its inverse is x=log4(y) For the function y=ln(x-2), its inverse is x=ey+2 By using the properties of logarithms, especially the fact that a number raised to a logarithm of base itself equals the argument of the logarithm: aloga(b)=b you can see that an exponential function with x as the independent variable of the form y=f(x) can be transformed into a function with y as the independent variable, x=f(y), by making it a logarithmic function. For a generalization: y=ax transforms to x=loga(y) and vice-versa Graphically, the logarithmic function is the corresponding exponential function reflected by the line y = x.
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
