Cosx+2=−x3+3x Using Newton's method as discussed in the lecture, find the value of x for which f(x∗)=0. Your answer should be real; increase the tolerance to verify if any imaginary components go to zero. For reference, this is the code we developed. You may also import and use scipy. optimize. newton if you prefer. A version of this question will be asked on a future quiz. def dfdx( f, x,h=1e-3 ): return ( f( x+h ) - f( x ) ) / h def newton( f, x0,tol=1e-3 ): d = abs( 0 - f( x0 ) ) while d > tol: x0 = x0 - f( x0 ) / dfdx( f, x0 ) d = abs( 0 - f( x0 ) ) return ( x0,f( x0 ) )

Write a defining table and then a program that determines if you can sleep in or not. your program should get all its input from your computer’s clock. on all weekdays (monday through friday) that are not holidays, your program should output “get up! ” on all other days (weekends and holidays), your program should output “sleep in.” the three holidays that your program must check for are january 1 (new year’s day), july 4 (u.s. independence day), and december 25 (christmas). you don’t need to include other holidays in your program because most other holidays do not occur on a fixed day each year.
