expand (csc(x)+sec(x))^2

expand

(csc (x) + sec (x))^{2}

csc^{2} (x) + 2 csc (x) sec (x) + sec^{2} (x)

Solution steps

(csc (x) + sec (x))^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(csc (x) + sec (x))^{2} = csc^{2} (x) + 2 csc (x) sec (x) + sec^{2} (x)

= csc^{2} (x) + 2 csc (x) sec (x) + sec^{2} (x)

(250 - \frac{x}{20}) x

(4 + 4 x) x^{3} e^{4 x}

11 (6 + 3)

- (21 + 4) \cdot (12 x^{5} - 5)

2 (x + 5 - 5 ln ∣ x + 5 ∣)
