Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
Answer:
i believe it is the 2nd one
Step-by-step explanation:
Answer:
(k+10f) (k-5f)
Step-by-step explanation:
k^2+5kf-50f^2
What 2 numbers multiply to -50 and add to +5
10 *-5 = -50
10+-5 = 5
(k+10f) (k-5f)
Answer:
(3,8)
Step-by-step explanation:
f(3)= 4 so y=f(3) +4 y =8 when x =3
