1.	Find the equation of the normal to the curve 2y=x2, which passes through the point (2, 1). OR Separate the interval [0,π2] into subintervals in which f(x)=sin4 x+cos4 x is strictly increasing or strictly decreasing.
Answer» Find the equation of the normal to the curve $2 y = x^{2}$ , which passes through the point (2, 1). OR Separate the interval $[\begin{matrix} 0, \frac{π}{2} \end{matrix}]$ into subintervals in which $f (x) = s i n^{4} x + c o s^{4} x$ is strictly increasing or strictly decreasing.
