Answer:

Arcsin(X) is the inverse function of the Sin function.

This means that Arcsin(X) gives you the value Y that you need to input in the function of Sin in order to have Sin(Y) = X

Here you can see that we have Arcsin(2), this would be equal to a number that when you put it inside the sin function, you have

Sin(Y) = 2, but as you know, the range of the sin function is from -1 to 1, so you never can have Sin(Y) = 2, this is why this expression can not be simplified.

This is not possible because arcsin is the angle that will give you a sine value of 2.  Sine values range from -1 to 1; there is no angle that will give you a sine of 2.

7-0.3×&gt;4<br>solve for x​
Troyanec [42]

Answer:

x<10

Step-by-step explanation:

Add '-7' to each side of the equation.

7 + -7 + -0.3x = 4 + -7

Combine like terms: 7 + -7 = 0

0 + -0.3x = 4 + -7

-0.3x = 4 + -7

Combine like terms: 4 + -7 = -3

-0.3x = -3

Divide each side by '-0.3'.

x = 10

Simplifying

x = 10

Whats the value of yif y=cos(arcsin1/2)
Setler [38]

arcsin(1/2) means "the angle whose sine is 1/2".

That's 30° .

y = cos(30°) = (1/2)√3 = about 0.866 .
