simplify 9sin((n+2)pi)-9sin(npi)

simplify

9 sin ((n + 2) π) - 9 sin (nπ)

9 sin (π (n + 2))

Solution steps

9 sin ((n + 2) π) - 9 sin (nπ)

Use the basic trigonometric identity:

sin (nπ) = 0

= 9 sin (π (2 + n)) - 9 \cdot 0

Refine

= 9 sin (π (n + 2))

cos (A - 18 0^{\circ})

cos^{4} (8 x + \frac{π}{6}) d x

2 sin (18 0^{\circ} - a)

\frac{cot ( x ) + tan ( π - x )}{2}

tan (3 π - x)
