Chapter 2.3, Problem 4E

Use the Secant method to find solutions accurate to within ${10}^{-5}$ for the following problems.

1. $2x\cos 2x-{(x-2)}^2=0$ on [2,3] and on [3,4]
2. ${(x-2)}^2-\ln x=0$ on [1,2] and on [e, 4]
3. $e^x-3x^2=0$ on [0,1] and on [3,5]
4. $\sin x-e^{-x}=0$ on [0,1], on [3,4] and on [6,7]
