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.
Answer:
0.3
30%
Step-by-step explanation:
To write 15/50 as a percent, you have to multiply the fraction by 100
x 100
dividing 100 by 50 gives 2
15 x 2 = 30%
to convert 15/50 to a decimal, first simply the fraction.
Both the numerator and denominator can be divided by 5
3/10
the next step is to divide the numerator by the denominator
3/10 = 0.3
