Homework Statement
Use a graphing calculator or computer to verify the given linear approximation at a = 0. Then determine the values of x for which the linear approximation is accurate to within 0.1. (Round the answers to two decimal places.)
tan(x) ≈ x
Homework Equations
derivative of tan(x) = sec^2(x)
The Attempt at a Solution
f(0)= tan(0)=0
fprime(0)= sec^2(0)= 1
L(x)=f(a)+fprime(a)(x-a)
L(x)=0+1(x-0)
L(x)=x
