1.	A curve is represented parametrically by the equations x=f(t)=aln(bt) and y=g(t)=b−ln(at);a,b>0 and a≠1,b≠1 where t∈R.The value of d2ydx2 at the point where f(t)=g(t) is
Answer» A curve is represented parametrically by the equations $x = f (t) = a^{ln (b^{t})}$ and $y = g (t) = b^{- ln (a^{t})}; a, b > 0$ and $a \neq 1, b \neq 1$ where $t \in R$ . The value of $\frac{d^{2} y}{d x^{2}}$ at the point where $f (t) = g (t)$ is
