erweitern (csc(a)+1)(sec(a)-tan(a))

Lösung

erweitern

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

csc (a) sec (a) - csc (a) tan (a) + sec (a) - tan (a)

Schritte zur Lösung

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

Apply FOIL method

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

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

e x p an d - \frac{5 ( - 2 y + x )}{4}

e x p an d \frac{2 ( 5 + s ^{2} )}{( s - 2 ) ( s + 2 ) ( s ^{2} + 4 )}

e x p an d 0.2707065 (\frac{1}{π} arctan (\frac{0.15}{x}) + 0.5)

e x p an d lo g_{10} (7 x^{3})
