integral of 9cos(x)+7sin(x)

\int 9 cos (x) + 7 sin (x) d x

9 sin (x) - 7 cos (x) + C

Solution steps

\int 9 cos (x) + 7 sin (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

= \int 9 cos (x) d x + \int 7 sin (x) d x

\int 9 cos (x) d x = 9 sin (x)

\int 7 sin (x) d x = - 7 cos (x)

= 9 sin (x) - 7 cos (x)

Add a constant to the solution

= 9 sin (x) - 7 cos (x) + C

\int sec^{3} (x) csc (x) d x

\int ln (\frac{x}{5}) d x

\int \frac{( 38 x + 2 )}{x ^{2} + 4} d x

\int x (x - x) d x

\int x^{4} + 2 d x
