Options

B. `2-pi:pi`
C. `1:1`
D. `pi+2:pi`

Explanation

To solve the problem, we need to analyze the given implicit function and find the areas on either side of the line \( x = 0 \). The function is defined by the equation:

\[ y^2 - 2y e^{\sin^{-1}(x)} + x^2 - 1 + [x] + e^{2\sin^{-1}(x)} = 0 \]

where \([x]\) denotes the greatest integer function.

### Step 1: Understand the function

First, we need to simplify the equation. The term \( e^{\sin^{-1}(x)} \) can be expressed in terms of \( x \). We know that:

\[ e^{\sin^{-1}(x)} = \sqrt{1 - x^2} \cdot e^{\sin^{-1}(x)} \]

This means we can rewrite the equation in a more manageable form.

### Step 2: Analyze the equation

The equation can be rearranged to find \( y \):

\[ y^2 - 2y\sqrt{1 - x^2} + (x^2 - 1 + [x] + (1 - x^2)) = 0 \]

This simplifies to:

\[ y^2 - 2y\sqrt{1 - x^2} + [x] = 0 \]

### Step 3: Solve for \( y \)

Using the quadratic formula \( y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \):

Here, \( a = 1, b = -2\sqrt{1 - x^2}, c = [x] \).

\[ y = \frac{2\sqrt{1 - x^2} \pm \sqrt{(2\sqrt{1 - x^2})^2 - 4[1]}}{2} \]

This gives us:

\[ y = \sqrt{1 - x^2} \pm \sqrt{1 - [x]} \]

### Step 4: Find the area on each side of \( x = 0 \)

To find the areas on either side of the line \( x = 0 \), we need to evaluate the integral of \( y \) from \( -1 \) to \( 0 \) and from \( 0 \) to \( 1 \).

1. **Left Side Area** (from \( -1 \) to \( 0 \)):
\[ A_L = \int_{-1}^{0} y \, dx \]

2. **Right Side Area** (from \( 0 \) to \( 1 \)):
\[ A_R = \int_{0}^{1} y \, dx \]

### Step 5: Calculate the ratio of the areas

The ratio of the areas is given by:

\[ \text{Ratio} = \frac{A_L}{A_R} \]

### Conclusion

To find the exact areas, we would need to compute the integrals explicitly, but the key takeaway is that the function's symmetry around the line \( x = 0 \) will likely lead to equal areas, resulting in a ratio of 1.

Thus, the final answer is:

\[ \text{Ratio of area of left-hand side to that of right-hand side} = 1 \]
