expand (sin(x)-8)sin(x)+7

expand

(sin (x) - 8) sin (x) + 7

sin^{2} (x) - 8 sin (x) + 7

Solution steps

(sin (x) - 8) sin (x) + 7

= sin (x) (sin (x) - 8) + 7

Expand

sin (x) (sin (x) - 8) : sin^{2} (x) - 8 sin (x)

= sin^{2} (x) - 8 sin (x) + 7

(3 x - \frac{4}{x})^{8}

(y^{3} + 3 x y^{2}) (5 + sec (y))

\frac{2 ( 4 - 7 )}{3}

\frac{1}{x ^{2} ( x ^{2} + 6 x + 7 )}

(- \frac{x ^{5}}{2} + y) (4 x^{2} - x y + y^{3})
