Problem: Plot the given trigonometric function.
Example:
trignometry_plot(fn=math.sin, plot_char="#")

Solution in Python:
import math
def trignometry_plot(fn=math.sin, n_x_steps=30, y_orig=40,
y_range=30, plot_char="."):

pi = 3.14159
for xi in range(n_x_steps+1):
x = 2 * pi / n_x_steps * xi
y = y_orig + y_range * fn(x)
row = ""
if y >= 0:
for i in range(y):
row += " "
row += plot_char
print row
Concepts Learned: Nested loops, trigonometric functions.
