expand 4(csc(x)+cot(x))(1-cos(x))

expand

4 (csc (x) + cot (x)) (1 - cos (x))

4 sin (x)

Solution steps

4 (csc (x) + cot (x)) (1 - cos (x))

Apply FOIL method

(csc (x) + cot (x)) (1 - cos (x)) : sin (x)

= 4 sin (x)

\frac{3 ( 3 ^{n} - 1 )}{2}

3 (- 7 - 2)

(r - 3)^{2}

\frac{( x ^{2} + 3 x - 2 )}{( ( x ^{2} - 1 ) ( x - 2 ) )}

(3 sin (x) - 3) (2 cos (x) + 1)
