(twenty-five *sin(five *x) - ten *cos(five *x)/x + two *sin(five *x)/x^ two)/x = zero
(25 multiply by sinus of (5 multiply by x) minus 10 multiply by co sinus of e of (5 multiply by x) divide by x plus 2 multiply by sinus of (5 multiply by x) divide by x squared ) divide by x equally 0
(twenty minus five multiply by sinus of (five multiply by x) minus ten multiply by co sinus of e of (five multiply by x) divide by x plus two multiply by sinus of (five multiply by x) divide by x to the power of two) divide by x equally zero
