The necessary and sufficient condition for the reflection of f in y=x to be the graph of a function is that f is one-to-one. Inverse functions are formed by taking the ‘inverse operation’ or ‘undoing’ the operation of the function. however, the inverse is not always a function. ...
INVERSETRIGONOMETRICFUNCTIONS Notes
Notes The inverse function, TAN, takes the angle in radians as the argument and returns the tangent. See also ATAN2 and COT. ATAN2 Syntax ATAN2(y number, x number) Output Number (angle in radians) Definition Returns the arctangent (angle) between two numbers (<y number> and <x number...
These classroom notes are focused on undergraduate students' understanding of the polysemous symbol of superscript (−1), which can be interpreted as a reciprocal or an inverse function. Examination of 240 scripts in a mid-term test identified that some first-year students struggle with choosing...
Hyperbolas are built from inverse functions, like $y = \frac{1}{x}$. It's a simple, useful relationship: what's the inverse of $x=2$? $y=1/2$. Multiply them and we undo all scaling: $xy=1$. A burning math question might be: sure, we have this inverse relationship, but what...
