Example text

Py with a main() that uses nested loops to test your function thoroughly. Project: Newton’s Method Newton’s method is a powerful technique for numerically computing the zeros of differentiable functions. It is an iterative technique, meaning that instead of applying a formula to directly compute the answer, it repeatedly tries to compute a better approximation until the desired accuracy is reached. Iteration is just a fancy word for repetition, which we know how to do in Python using for loops and while loops.

20 Write a function sort3(x, y, z) that returns the three values x, y, and z in sorted order (a, b, c), where a ≤ b ≤ c. Do not use any built-in Python sorting functions, but you may put if statements inside of other if statements. Write a main() that thoroughly tests your function. 20. Use multiple assignment (see page 95) to store the return values of sort3(). 22 Write a function myabs(x) that returns | x |, the absolute value of x, which is given by: { x if x ≥ 0 |x| = −x otherwise Do not use the built-in Python function abs(x).

The turtle holds a pen, and if the pen is down when the turtle moves, then a line will be drawn. The turtle may also move with the pen up or initiate other types of drawing such as “stamping” its own shape or drawing dots. 1 uses the following functions from the Python turtle module: penup() forward(x) left(theta) stamp() clearstamps(n) ycor() Stop drawing turtle path. Move forward x. Turn left angle theta (default is degrees). Draw turtle shape at current location. Delete first n stamps (if n is positive).
