If `sin (sin^(-1).(1)/(5) + cos^(-1) x) = 1`, then find the value of x

Explanation

To solve the equation \( \sin\left(\sin^{-1}\left(\frac{1}{5}\right) + \cos^{-1}(x)\right) = 1 \), we can follow these steps:

### Step 1: Understand the Equation
The equation states that the sine of the sum of two angles equals 1. The sine function equals 1 at \( \frac{\pi}{2} \) (or \( 90^\circ \)). Therefore, we can set up the equation:

\[ \sin\left(\sin^{-1}\left(\frac{1}{5}\right) + \cos^{-1}(x)\right) = 1 \implies \sin^{-1}\left(\frac{1}{5}\right) + \cos^{-1}(x) = \frac{\pi}{2} \]
