expand (sin(x)+xcos(x))(x+cos(x))

expand

(sin (x) + x cos (x)) (x + cos (x))

x sin (x) + cos (x) sin (x) + x^{2} cos (x) + x cos^{2} (x)

Solution steps

(sin (x) + x cos (x)) (x + cos (x))

Apply FOIL method

(sin (x) + x cos (x)) (x + cos (x)) : x sin (x) + cos (x) sin (x) + x^{2} cos (x) + x cos^{2} (x)

= x sin (x) + cos (x) sin (x) + x^{2} cos (x) + x cos^{2} (x)

P_{15} (P_{6} + P_{7} x + x^{2})^{3}

(tan (x) - 4) (tan (x) + 4) (tan (x) - 2) (tan (x) + 2)

5 x (x - 8 x)

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

(1 + ln (2))^{3}
