integral of cos((pit)/(12))

\int cos (\frac{π t}{12}) d t

\frac{12}{π} sin (\frac{π t}{12}) + C

Solution steps

\int cos (\frac{π t}{12}) d t

Apply u-substitution

= \int cos (u) \frac{12}{π} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{12}{π} \cdot \int cos (u) d u

Use the common integral:

\int cos (u) d u = sin (u)

= \frac{12}{π} sin (u)

Substitute back

u = \frac{π t}{12}

= \frac{12}{π} sin (\frac{π t}{12})

Add a constant to the solution

= \frac{12}{π} sin (\frac{π t}{12}) + C
