Impara online a risolvere i problemi di passo dopo passo. Expand and simplify the trigonometric expression (1/2-1/2cos(2x))^3. Applicare la formula: \left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3, dove a=\frac{1}{2}, b=-\frac{1}{2}\cos\left(2x\right) e a+b=\frac{1}{2}-\frac{1}{2}\cos\left(2x\right). Applicare la formula: a^b=a^b, dove a=\frac{1}{2}, b=3 e a^b=\left(\frac{1}{2}\right)^3. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=1, b=4, c=3, a/b=\frac{1}{4} e ca/b=3\cdot \left(\frac{1}{4}\right)\cdot \left(-\frac{1}{2}\right)\cos\left(2x\right). Applicare la formula: ab=ab, dove ab=3\cdot 1, a=3 e b=1.
