y = (1/x )x
दोनों तरफ से log लेने पर
log y = x log(1/x)
log y = x(log 1 - log x)
log y = x(-log x)
y के सापेक्ष अवकलन कीजिए
1/y × dy/dx = -( 1 + log x)
dy/dx = -(1/x)x(1 + log x
पुनः x के सापेक्ष अवकलन कीजिए
d2y/dx2 = -(dy/dx(1 + logx) +y(1/x)
d2y/dx2 = -(-(1/x)x(1+ log x)2 + (1/x)x+
अतः विकल्प 2 सही है।
