7 2/5 x 6 1/4
14/5 x 6/4
84/20
21/5
=4.2
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.
Check the picture below.
notice, it simply got mirrored over the vertical y-axis.
Answer:
y=22 x=18
Step-by-step explanation:
The answer is 12
Explanation: as you replace -2 it will give 4 so when u add 4 to 8 it equals to 12
