The linear approximation L(x)=f(a)+f′(a)(x−a) is the tangent line to the graph of y=f(x) at the point (a,f(a)). It has the property that L(a)=f(a) and L′(a)=f′(a). a) Find the expression for the Quadratic approximation to the graph of y=f(x) at the point (a,f(a)),Q(x)=A+B(x−a)+C(x−a)2 so that Q(a)=f(a),Q′(a)=f′(a), and Q′′(a)=f′′(a) b) Use the result from part (a) to find the Linear and Quadratic approximations to the function f(x)=cosx at the point (0,1).
