Step-by-step explanation:
y = (cos x)^(sin x)
Take log both sides.
ln y = ln ((cos x)^(sin x))
ln y = (sin x) ln (cos x)
Take derivative.
1/y dy/dx = (sin x) (1/cos x) (-sin x) + (cos x) ln (cos x)
dy/dx = y [ (cos x) ln (cos x) − sin x tan x ]
dy/dx = (cos x)^(sin x) [ (cos x) ln (cos x) − sin x tan x ]
Your answer is correct.
The answer
if Marco wants to create a new circle using GX as a radius,
so GX = r = 10 cm + 16 cm = 26 cm
the area of a circle is
A = pie x r², so the new circle's area should be A = pie x 26² = 676 pie cm²
the true answer is
<span>D. 676 pie cm2</span>
I know the 1st and last one but i’m not sure on the rest sorry :(
Simplify them until they can be simplified no more, then compare both sides.
A c d hope this will help u
