expand (1+cos(α))(1+csc(α))

expand

(1 + cos (α)) (1 + csc (α))

cos (α) + csc (α) + cot (α) + 1

Solution steps

(1 + cos (α)) (1 + csc (α))

Apply FOIL method

(1 + cos (α)) (1 + csc (α)) : cos (α) + csc (α) + cot (α) + 1

= cos (α) + csc (α) + cot (α) + 1

(a + b x + 2 c x^{2} + 3 d x^{3} + 4 e x^{4})^{2}

\frac{4 ( x + 1 )}{5 ( x + 3 )}

(X^{5} - \frac{1}{3})^{3}

\frac{x ( x - 1 )}{( 4 + x ) ( 4 - x )}

5 (6 - 8)
