Answer:
pp
Step-by-step explanation:
The answer is 2(3x-y)+5(x+2y).
The derivative of sec x is equal to sec x tan x. The derivative of the first derivative can be determined using the rule of products. The derivative is equal to sec x sec^2 x + tan x * sec x tan x. The simplified answer is sec^3 x + sec^2 x tan x equal to sec^2 x ( sec x + tanx )
The answer is b,a,c
the reason I know this is because the angle opposite to the largest side is the greatest angle, the angle across from the smallest side is the smallest angle
