integral of-284244sin(120pix+pi/3)

\int - 284244 sin (120 π x + \frac{π}{3}) d x

- 284244 (\frac{1}{80 3 π} sin (120 π x) - \frac{1}{240 π} cos (120 π x)) + C

Solution steps

\int - 284244 sin (120 π x + \frac{π}{3}) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 284244 \cdot \int sin (120 π x + \frac{π}{3}) d x

Rewrite using trig identities

= - 284244 \cdot \int \frac{3}{2} cos (120 π x) + \frac{1}{2} sin (120 π x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - 284244 (\int \frac{3}{2} cos (120 π x) d x + \int \frac{1}{2} sin (120 π x) d x)

\int \frac{3}{2} cos (120 π x) d x = \frac{1}{80 3 π} sin (120 π x)

\int \frac{1}{2} sin (120 π x) d x = - \frac{1}{240 π} cos (120 π x)

= - 284244 (\frac{1}{80 3 π} sin (120 π x) - \frac{1}{240 π} cos (120 π x))

Add a constant to the solution

= - 284244 (\frac{1}{80 3 π} sin (120 π x) - \frac{1}{240 π} cos (120 π x)) + C

\int 3 e^{x} - 2 sin (x) d x

\int \frac{1}{x ^{6} - 8 x ^{3}} d x

\int - x^{3} e^{x} d x

\int \frac{sec ^{4} ( x )}{sec ^{2} ( x ) - 1} d x

\int \frac{4 z}{5 z ^{2} + 2} d z
