sec (y) (tan (y) - sec (y)) d y

sec (y) tan (y) d y - sec^{2} (y) d y

Schritte zur Lösung

sec (y) (tan (y) - sec (y)) d y

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = sec (y) d y, b = tan (y), c = sec (y)

= sec (y) d y tan (y) - sec (y) d y sec (y)

= sec (y) tan (y) d y - sec (y) sec (y) d y

sec (y) sec (y) d y = sec^{2} (y) d y

= sec (y) tan (y) d y - sec^{2} (y) d y

e x p an d H (8 - t) (sin (t - 1) - sin (t - 4))

e x p an d \frac{5 s ^{2} + 4}{( s ^{2} + 17 ) ( s - 1 )}

e x p an d e^{2 x} (x^{3} + 1)

e x p an d (3 a + 4 c = 8, 2) - (2 a + 3 c = 58)

e x p an d (sin (a) + sin (b))^{2} + cos (a) - cos (b)
