integral of 7cos(x)+3sin(x)

\int 7 cos (x) + 3 sin (x) d x

7 sin (x) - 3 cos (x) + C

Solution steps

\int 7 cos (x) + 3 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 7 cos (x) d x + \int 3 sin (x) d x

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

\int 3 sin (x) d x = - 3 cos (x)

= 7 sin (x) - 3 cos (x)

Add a constant to the solution

= 7 sin (x) - 3 cos (x) + C

\int \frac{1}{x ( x ^{6} + 2 )} d x

\int (2 - 2 x)^{7} d x

\int u \cdot e^{- u} d u

\int (ln (ln (x)) + \frac{1}{ln ( x )}) d x

\int \frac{x ^{3}}{7 + x ^{2}} d x
