expand sqrt(2)(x-pi/2)

expand

2 (x - \frac{π}{2})

2 x - \frac{π}{2}

Solution steps

2 (x - \frac{π}{2})

Apply the distributive law:

a (b - c) = ab - a c

a = 2, b = x, c = \frac{π}{2}

= 2 x - 2 \frac{π}{2}

2 \frac{π}{2} = \frac{π}{2}

= 2 x - \frac{π}{2}

\frac{x ^{9} y - x ^{9}}{( x ^{6} + y ^{2} - 2 y + 1 ) ^{2}}

(e^{x} - e^{- x}) 5 (e^{x} + e^{- x})

\frac{1}{z ( z - 10 ) ( z - 1 )}

d y (x + y^{3} - y^{2} \cdot sin (x))

(x^{2} + 1)^{2} d x
