Sum of series:
sin(nx)*(5-(3*n))
ln(k/(k+1))
100
sin(n^n*factorial(n))/2^n
Identical expressions
sin(nx)*(five -(three *n))
sinus of (nx) multiply by (5 minus (3 multiply by n))
sinus of (nx) multiply by (five minus (three multiply by n))
sin(nx)(5-(3n))
sinnx5-3n
Similar expressions
sin(nx)*(5+(3*n))

Sum of series/ sin(nx)*(5-(3*n))
