what is the point of inverse functions? i heard it helps with temperature(Fahrenheit and Celsius) conversions, but i don't understand how it helps and how it is faster than just solving for it.

Answer 1

0ne example of importance is inverse trigonometric functions, which often appear in the solution to physical problems and in integral calculus.

Another example is e^x, the inverse function of ln(x).

Knowing the inverse function is also useful when one must solve many times for x when y is known, since solving the y(x) equation for x each time is more time consuming.
