cot x = cos x / sin x
tan x = sin x / cos x
(Find common denominators)
cosx/sinx * cosx/cosx = cos^2x/sinxcosx
sinx/cosx * sinx/sinx = sin^2x/sinxcosx
(Now we can combine them)
csc / (sin^2x+cos^2x / sinxcosx)
(Simplify)
csc*sinx*cosx / sin^2x+cos^2x
sin^2x + cos^2x = 1
csc*sinx*cosx / (1)
csc*sinx*cosx
csc = 1/sinx
1/sinx*sinx = 1
(1)*cosx = cosx

The first touchscreen was invented in 1965 by Eric A. Johnson who worked at the Royal Radar Establishment in Malvern, England. His first article, "Touch display—a novel input/output device for computers" describes his work and features a diagram of the design. 1982.
Answer:
There is no problem. Your main function returns zero to the operating system, which is reported as the exit code. Everything is working correct.
The fix to the problem in the code is as follows:
def sum(a, b):
total = a + b
print(total)
sum(1, 0)
<h3>How to determine the problem and the fix to the problem?</h3>
The code is given as:
def sum(a, b):
total = a + b
print(total)
sum(total, a)
sum(1, 0)
When the above code is run, one or both of the following would occur
- An infinite loop because the program cannot end the recursion
- An error when the maximum memory is used
The problem in the code is that, the recursive function do not have a condition to end itself.
The fix to the problem is to remove the recursive definition.
So, we have the fixed code to be
def sum(a, b):
total = a + b
print(total)
sum(1, 0)
