(a) $f(x) = \frac{{{{\cos }^2}x + {{\sin }^4}x}}{{{{\sin }^2}x + {{\cos }^4}x}}$

==> $f(x) = \frac{{{{\cos }^2}x + {{\sin }^2}x(1 - {{\cos }^2}x)}}{{{{\sin }^2}x + {{\cos }^2}x(1 - {{\sin }^2}x)}}$

==> $f(x) = \frac{{{{\sin }^2}x + {{\cos }^2}x - {{\sin }^2}x{{\cos }^2}x}}{{{{\sin }^2}x + {{\cos }^2}x - {{\sin }^2}x{{\cos }^2}x}}$

==> $f(x) = 1$ ==> $f(2002) = 1$.

यदि $f(x) = \frac{{{{\cos }^2}x + {{\sin }^4}x}}{{{{\sin }^2}x + {{\cos }^4}x}}$, $x \in R$ के लिए, तब $f(2002) = $
