(two *sin(x)^ two - seven *cos(x)^ two)*sin(x) = zero
(2 multiply by sinus of (x) squared minus 7 multiply by co sinus of e of (x) squared ) multiply by sinus of (x) equally 0
(two multiply by sinus of (x) to the power of two minus seven multiply by co sinus of e of (x) to the power of two) multiply by sinus of (x) equally zero
(2*sin(x)2 - 7*cos(x)2)*sin(x) = 0
2*sinx2 - 7*cosx2*sinx = 0
(2*sin(x)² - 7*cos(x)²)*sin(x) = 0
(2*sin(x) to the power of 2 - 7*cos(x) to the power of 2)*sin(x) = 0
