Hiiiiiiiiiiiiiiiiiiiiiiiii
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
Step-by-step explanation:
10. |-41|= 41
12. -|1.5|= -1.5
Includes critical information you need to identify the chemical
, Includes warnings about the chemical
, Legible are the requirements for chemical labels
<u>Step-by-step explanation:</u>
Labels need to produce guidance on how to manage the chemical so that chemical users are notified about how to guard themselves. That data about chemical hazards be dispatched on labels using quick visual notations (Legible) to inform the user, granting instant identification of the hazards.
Labels, as described in the HCS, are a relevant group of written, printed or graphic information elements concerning a hazardous chemical that are attached to, printed on, or added to the immediate container of a hazardous chemical, or to the outside packaging.
