Web7 feb. 2024 · That's not a mathematical well made rule, but accurate for each situation this appears. Everytime any of your functions has a 0 outcome it's restricted. When you divide by sin or cos then the resulting equation has restrictions. @Dr. Sonnhard Graubner has pointed out that your domain is restricted and how it is restricted. WebAs you can see below, the inverse cos -1 (1) is 0° or, in radian measure, 0 . '1' represents the maximum value of the cosine function. It happens at 0 and then again at 2Π, 4Π, 6Π etc.. (see second graph below.) Below is a picture of the graph of cos (x) with over the domain of 0 ≤x ≤4Π with cos -1 (1) indicted by the black dot.

WebThis removes the sine from one side of the equation, but puts the "arcsin" on the other side, because you have to do the same thing to both sides of the equal sign. That's the only way to remove a variable from a trig function. No multiplication, addition, or exponentiation can penetrate its borders. You have to use the inverse (arcsin) function.
