expand (2sin(x)+1)(cos(x)+1)

expand

(2 sin (x) + 1) (cos (x) + 1)

cos (x) + 2 sin (x) + sin (2 x) + 1

Solution steps

(2 sin (x) + 1) (cos (x) + 1)

Apply FOIL method

(2 sin (x) + 1) (cos (x) + 1) : cos (x) + 2 sin (x) + sin (2 x) + 1

= cos (x) + 2 sin (x) + sin (2 x) + 1

(5 x + 3)^{6} d x

(6 x^{2} - 3 x^{3}) d x

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

(x + 1) (\frac{x}{x + 1} + 1)

\frac{x}{( 1 + 7 x ) ^{2}}
