expand (1-t)sin(pit)(1-2t)

expand

(1 - t) sin (π t) (1 - 2 t)

2 t^{2} sin (π t) - 3 t sin (π t) + sin (π t)

Solution steps

(1 - t) sin (π t) (1 - 2 t)

= sin (π t) (1 - t) (1 - 2 t)

Expand

(1 - t) (1 - 2 t) : 2 t^{2} - 3 t + 1

= sin (π t) (2 t^{2} - 3 t + 1)

Expand

sin (π t) (2 t^{2} - 3 t + 1) : 2 t^{2} sin (π t) - 3 t sin (π t) + sin (π t)

= 2 t^{2} sin (π t) - 3 t sin (π t) + sin (π t)

\frac{d}{d y} ((x) (x + 2 x y))

\frac{( x - 1 ) ( x - 5 )}{( x - 2 ) ( x - 4 )}

\frac{( 4 k - 7 ) ^{2}}{9}

(x + y = 8,) - (y + z = 7)

A (3 + 2 x, 5)
