expand (3sin(377t)-1.5)^2

expand

(3 sin (377 t) - 1.5)^{2}

9 sin^{2} (377 t) - 9 sin (377 t) + 2.25

Solution steps

(3 sin (377 t) - 1.5)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(3 sin (377 t) - 1.5)^{2} = (3 sin (377 t))^{2} - 2 \cdot 3 sin (377 t) \cdot 1.5 + 1. 5^{2}

= (3 sin (377 t))^{2} - 2 \cdot 3 sin (377 t) \cdot 1.5 + 1. 5^{2}

Simplify

(3 sin (377 t))^{2} - 2 \cdot 3 sin (377 t) \cdot 1.5 + 1. 5^{2} : 9 sin^{2} (377 t) - 9 sin (377 t) + 2.25

= 9 sin^{2} (377 t) - 9 sin (377 t) + 2.25

2 sin (6) (x + \frac{π}{3})

(2 - 5 a)^{2}

\frac{1 - e ^{- s} + s ^{2} + 4 s}{s ( s ^{2} + 4 s + 5 )}

(3 sin (x) - 3 cos (x))^{2}

sin (2 (t - x))
