Question

simplifica cada expresion utilizando identidades fundamentales
cosα ×secα+cot²α
cos²x /senxtanx-1

Answer 1

Explicación paso a paso:

cos(a)×sec(a)+cot^2(a)

cos(a)×(1/cos(a))+cot^2(a)

1+cot^2(a)

csc^2(a)

Answer 2

sec a = 1/Cos a

csc a= 1/ sen a

sec^2 x - tan^2 x = 1

csc^2 x - cot^2 x = 1

cosa × (1/cosa) + (csc^2 a -1)

1+ csc^2 a -1

csc^2 a

cos^2 x / senx × (senx/cosx) -1

cos^2 x / (sen^2 x / cosx) -1

cos^3 x / sen^2 x -1

cos^3 x / 1- cos^2 x -1
