simplify-2(sin(pin)-pincos(pin))

simplify

- 2 (sin (πn) - πn cos (πn))

2 π (- 1)^{n} n

Solution steps

- 2 (sin (πn) - πn cos (πn))

Use the basic trigonometric identity:

sin (nπ) = 0

= - 2 (0 - nπ cos (nπ))

Use the basic trigonometric identity:

cos (nπ) = (- 1)^{n}

= - 2 (0 - nπ (- 1)^{n})

Simplify

= 2 π (- 1)^{n} n

sin (π + 2 y) - sin (0 + 2 y)

sin (tan (- 1) (x))

cos (arctan (7 x^{3}))

sec (\frac{25 π}{2} - x)

cos (cos^{2} (x) - 1)
