s=2

Explanation:

Given: y=xx2+sin1(x),(0x1)

Using the formula:

s=ba1+(dydx)2dx

The first derivative is:

dydx=12x2xx2+121xx

Substitute the known values into the formula:

s=10 1+(12x2xx2+121xx)2dx

Multiply the square:

s=101+x2xx2xxx2x1xxx2+14(xx2)+121xxx2x+14(1x)xdx

This simplifies to:

s=101xdx

s=2x10

s=2
