Find the Antiderivative cos(x/(2))

integral

cos (\frac{x}{( 2 )})

2 sin (\frac{x}{2}) + C

Solution steps

\int cos (\frac{x}{2}) d x

Apply u-substitution

: \int cos (u) \cdot 2 d u

= \int cos (u) \cdot 2 d u

Take the constant out:

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

= 2 \cdot \int cos (u) d u

Use the common integral:

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

= 2 sin (u)

Substitute back

u = \frac{x}{2}

= 2 sin (\frac{x}{2})

Add a constant to the solution

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

- \frac{d}{d x} (6^{x})

sec (2 x)

- \frac{d}{d x} y = 3 x^{2}

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

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