expand (2sin(x)-1)(sin(x)-1)

expand

(2 sin (x) - 1) (sin (x) - 1)

2 sin^{2} (x) - 3 sin (x) + 1

Solution steps

(2 sin (x) - 1) (sin (x) - 1)

Apply FOIL method

(2 sin (x) - 1) (sin (x) - 1) : 2 sin^{2} (x) - 3 sin (x) + 1

= 2 sin^{2} (x) - 3 sin (x) + 1

\frac{1}{2} (arcsin (x) + \frac{1}{2} sin (2 arcsin (x)))

\frac{π}{3} ((18 + y) (3 + \frac{y}{6})^{2} - (21 \cdot 3)^{2}) y

(1 + i t + t^{2})^{3}

\frac{5 x ^{2}}{( x ^{2} - 9 ) ^{2}}

4 (5 - sin (x))
