(a) Two function f(x) and g(x) are called orthogonal in the interval [ab] if they satisfy the condition
if(x) g(x)dx = 0. Show that if f(x)=L.g(x)=x, then they are orthogonal in the interval [-1,1]. Determine the
constants A and B so that the function h(x)=1+Ax+Bx², is orthogonal to f(x) and g(x) in the same interval.
