Explanation / Answer

1)Linearization of f(x) at x = a is L(x) = f(a) + f'(a) (x - a)

L(x)=15 sin (pi/4)+15cos(pi/4)(x-pi/4)

L(x)=(15/sqrt(2))(x-pi/4)=10.61(x-.79)

2)f(x)=sqrt(x)

lets take a=100

L(x)=10+1/(2sqrt(100))*(x-100)

L(x)=10+.05x-5=5+.05x

L(99.6)=5+.05*99.6=9.98

Note : L(x) is the linearized function not f(x)

3)f(x)=sinx

lets take a=0

L(x)=sin0+cos0(x-0)

L(x)=x

L(-.4)=-.4

Note : L(x) is the linearized function not f(x)
