Why does inverse trig functions have restrictions Function explanation

👉 Learn how to evaluate inverse trigonometric functions. The inverse trigonometric functions are used to obtain theta, the angle which yielded the trigonometric function value. It is usually helpful to use the calculator to calculate the inverse trigonometric functions, especially for non-special angles.

To calculate the inverse trigonometric function of a value using the calculator we press the second function button (shift) before pressing the trigonometric function button and then the number follows. This gives the inverse trigonometric function of the calculated value.

ok but what makes it restricted to those specific quadrants? why is arccos only in 1 & 2, and not idk like 3 & 4??? i dont get it

But like, how exactly do you know what exactly to restrict???
