-sin(x)^ seven + six *sin(x)^ five *cos(x)^ two = zero
minus sinus of (x) to the power of 7 plus 6 multiply by sinus of (x) to the power of 5 multiply by co sinus of e of (x) squared equally 0
minus sinus of (x) to the power of seven plus six multiply by sinus of (x) to the power of five multiply by co sinus of e of (x) to the power of two equally zero
-sin(x)7 + 6*sin(x)5*cos(x)2 = 0
-sinx7 + 6*sinx5*cosx2 = 0
-sin(x)⁷ + 6*sin(x)⁵*cos(x)² = 0
-sin(x) to the power of 7 + 6*sin(x) to the power of 5*cos(x) to the power of 2 = 0
