Algorithm for To calculate the sum. Sum=1-x2/2!+ x4/4!- x6/6!+ x8/8!- x10/10!

Objective:4

To calculate the sum. Sum=1-x²/2!+ x⁴/4!- x⁶/6!+ x⁸/8!- x¹⁰/10!

Algorithm:

main program:

Step 1: start

Step 2: declare x,i,n,s=0,c

Step 3: read x value

Step 4: for i=0 , n=0; i<=10; i=i+2, n++ goto step 5

Step 5: s=s+(pow(-1,n)*pow(x,i)/fact(i))

Step 6: print s value

Step 7: stop

Sub program:

Step 1: while x!=0 goto Step 2

Step 2: y=y+x; x—

Step 3: return y

Step 4: return to main program
