expand (2csc(x)-9)(cot(x)-2)

expand

(2 csc (x) - 9) (cot (x) - 2)

2 cot (x) csc (x) - 4 csc (x) - 9 cot (x) + 18

Solution steps

(2 csc (x) - 9) (cot (x) - 2)

Apply FOIL method

(2 csc (x) - 9) (cot (x) - 2) : 2 cot (x) csc (x) - 4 csc (x) - 9 cot (x) + 18

= 2 cot (x) csc (x) - 4 csc (x) - 9 cot (x) + 18

(1 - i 7)^{6}

\frac{12}{( x - 1 ) ( x + 1 )}

(98 π - 42) \cdot 6

(\frac{3}{x - 16} + 5 (100 - x)) (x - 16)

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