expand (sec(u)-tan(u))(csc(u)+1)

expand

(sec (u) - tan (u)) (csc (u) + 1)

csc (u) sec (u) + sec (u) - csc (u) tan (u) - tan (u)

Solution steps

(sec (u) - tan (u)) (csc (u) + 1)

Apply FOIL method

(sec (u) - tan (u)) (csc (u) + 1) : csc (u) sec (u) + sec (u) - csc (u) tan (u) - tan (u)

= csc (u) sec (u) + sec (u) - csc (u) tan (u) - tan (u)

f (x) = lo g_{5} (x) (x + 2)

(x - y i)^{4}

(x^{2} + \frac{3}{x})^{4}

b (5, - \frac{π}{3})

(2 t - 3) e^{(\frac{( t + 2 )}{3})}
