integral of 5cos(x)-4sin(x)

\int 5 cos (x) - 4 sin (x) d x

5 sin (x) + 4 cos (x) + C

Solution steps

\int 5 cos (x) - 4 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 5 cos (x) d x - \int 4 sin (x) d x

\int 5 cos (x) d x = 5 sin (x)

\int 4 sin (x) d x = - 4 cos (x)

= 5 sin (x) - (- 4 cos (x))

Simplify

= 5 sin (x) + 4 cos (x)

Add a constant to the solution

= 5 sin (x) + 4 cos (x) + C

\frac{d}{d x} ((2 x + 3)^{2})

f (x) = a^{4} + cos^{4} (x)

\int_{0}^{1} 2 π (2 - y) (4 y^{2}) d y

\int - sin (d) x d x
