integral of sin(x^2+2)

\int sin (x^{2} + 2) d x

sin (2) \frac{π}{2} C (\frac{2}{π} x) + cos (2) \frac{π}{2} § (\frac{2}{π} x) + C

Solution steps

\int sin (x^{2} + 2) d x

Rewrite using trig identities

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

\int cos (x^{2}) sin (2) d x = sin (2) \frac{π}{2} C (\frac{2}{π} x)

\int cos (2) sin (x^{2}) d x = cos (2) \frac{π}{2} § (\frac{2}{π} x)

= sin (2) \frac{π}{2} C (\frac{2}{π} x) + cos (2) \frac{π}{2} § (\frac{2}{π} x)

Add a constant to the solution

= sin (2) \frac{π}{2} C (\frac{2}{π} x) + cos (2) \frac{π}{2} § (\frac{2}{π} x) + C

\int \frac{tan ^{7} ( x )}{sec ^{8} ( x )} d x

\int \frac{a}{u ^{2} + a ^{2}} d u

\int \frac{2}{9 + x ^{2}} d x

\int (\frac{4}{3 t ^{2}} + \frac{7}{2 t}) d t

\int (3 x^{3} + 6 x)^{3} (3 x^{2} + 2) d x
