Answer #1

#source code:

import math
def fac(n):
   if(n<=0):
       return 1
   else:
       return n*fac(n-1)

print(fac(-1))

def cos1(x,n):
   z=2
   sum=1
   for i in range(0,n):
       if(i%2==0):
           sum=sum-((x**z)/fac(z))
           z=z+2
       else:
           sum=sum+((x**z)/fac(z))
           z=z+2
   return sum
def cos2(x,n):
   return cos1(x,n)
i=0.0
print("x\tcos(x)\tcos1(x,10)\tcos2(x,10)\n")
while(i<=2.0):
   print(str(i)+"\t"+str(math.cos(i))+"\t"+str(cos1(i,10))+"\t"+str(cos2(i,10)))
   i=round(i+0.1,1)
  
      
      

import math def fac(n) : if (n<=0): return 1 else: return n*fac (n-1) print (fac(-1)) def cosl(x,n): z=2 sum=1 for i in range

#output:

cos(x) cos1(x,10) cos2(x,10) 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.0 1.0 1.0 0.9950041652780258 0.9800665778412416 0.

    use python IDEL Please highlight the answer 1 ווCIוסטIT Errors and Exceptions. There are two main types of errors: syntax errors and runtime errors. Syntax errors are detected by the Python interpreter before the program execution during the parsing stage (parsing is a process, during which the Python interpreter analyzes the grammatical structure of the program). Runtime errors are errors in a program that are not detected by the Python interpreter during its parsing stage. They are further divided into...
