expand (2csc(x)-1)(csc(x)+1)

expand

(2 csc (x) - 1) (csc (x) + 1)

2 csc^{2} (x) + csc (x) - 1

Solution steps

(2 csc (x) - 1) (csc (x) + 1)

Apply FOIL method

(2 csc (x) - 1) (csc (x) + 1) : 2 csc^{2} (x) + csc (x) - 1

= 2 csc^{2} (x) + csc (x) - 1

(- 3, 5) y (7, - 3)

\frac{2}{2 π + 8} + \frac{16 π ^{3}}{( 2 π + 8 ) ^{2}}

\frac{n ^{2} ( n + 1 ) ^{2}}{4}

(- 3 + 2 i)^{6}

(y^{3} - 4 x y^{2} - 2 x^{3}) d x + x^{2} (2 y + x) d y
