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.
A) 36 means that there are 36 students taking Italian and music AT SAME TIME
b) 59 means that there are 59 students taking only music
c) 48 means that there are 48 students taking neither Italian nor music
d) Italian OR Music = 97 + 36 +59 = 192
e) Do not take Italian: 48 + 59 = 107
