expand (cos(a)-sin(a))(sec(a)+csc(a))

expand

(cos (a) - sin (a)) (sec (a) + csc (a))

cot (a) - tan (a)

Solution steps

(cos (a) - sin (a)) (sec (a) + csc (a))

Apply FOIL method

(cos (a) - sin (a)) (sec (a) + csc (a)) : cot (a) - tan (a)

= cot (a) - tan (a)

(s^{\frac{1}{2}} - t^{\frac{1}{2}})^{2}

2 x (e^{x} - 1) - 15

(a + b) (c + d) (e + f)

d o m (x^{2} - 4)

(x + 2) (x + \frac{5}{4}) (x + \frac{1}{2}) (x - \frac{1}{4}) (x - 1)
