(d^2)/(dx^2)(sin(x)+cos(x))

\frac{d ^{2}}{d x ^{2}} (sin (x) + cos (x))

- sin (x) - cos (x)

Solution steps

\frac{d ^{2}}{d x ^{2}} (sin (x) + cos (x))

\frac{d}{d x} (sin (x) + cos (x)) = cos (x) - sin (x)

= \frac{d}{d x} (cos (x) - sin (x))

\frac{d}{d x} (cos (x) - sin (x)) = - sin (x) - cos (x)

= - sin (x) - cos (x)

7 cos (π x), 8 x^{2} - 2, - 0.5, 0.5

\int e^{\frac{x}{6}} d x

\frac{2 t}{2 + t}

\int_{1}^{2} \frac{x}{x - 1} d x
