integral from-pi to pi of cos(n)x

\int_{- π}^{π} cos (n) x d x

0

Solution steps

\int_{- π}^{π} cos (n) x d x

If f(x) is an odd function and continuous at:

[- a, a]

then

\int_{- a}^{a} f (x) d x = 0

Parity of

cos (n) x :

Odd

= 0

\int_{1}^{5} \frac{z ^{2} + 4}{z} d z

\int_{0.5}^{1} x^{4} d x

\int_{0}^{2} 12 x^{3} + 3 x^{2} - 4 x d x

\int_{0}^{5} ∣ x^{2} - 9 ∣ d x

\int_{0}^{\frac{π}{3}} sin (x) cos (x) d x
