expand (2-sin(t))^2

expand

(2 - sin (t))^{2}

4 - 4 sin (t) + sin^{2} (t)

Solution steps

(2 - sin (t))^{2}

Apply Perfect Square Formula:

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

(2 - sin (t))^{2} = 2^{2} - 2 \cdot 2 sin (t) + sin^{2} (t)

= 2^{2} - 2 \cdot 2 sin (t) + sin^{2} (t)

Simplify

2^{2} - 2 \cdot 2 sin (t) + sin^{2} (t) : 4 - 4 sin (t) + sin^{2} (t)

= 4 - 4 sin (t) + sin^{2} (t)

(tan (2 x) + cot (2 x))^{2}

(x + 3) (x - 4)

- e^{3 x} (12 sin (2 x) - 5 cos (2 x))

(3 + j) (2 - j)

tan (x) (1 + cot^{3} (x)) + cot (x) (1 + tan^{3} (x)) + 2
