I’m pretty sure it’s answer a!
Answer:
dy/dx = x^sin(x) * (sin(x)/x + cos(x) * lnx)
Step-by-step explanation:
∵ y = x^sin(x)
∴㏑y = ㏑(x^sin(x)) = sinx * ㏑x --- by differentiating both sides with respect to x
(1/y)* dy/dx = sin(x)/x + cos(x) lnx
dy/dx = x^sin(x) * (sin(x)/x + cos(x) * lnx)
Answer:69 2/9 - 31 1/9 - (- 12 4/9) =
69 2/9 - 31 1/9 + 12 4/9 =
81 6/9 - 31 1/9 =
50 5/9 or 455/9 or 50.56 <==
Step-by-step explanation:
Answer:
,
Step-by-step explanation:
Note I'm using a, instead of theta to represent angles.
To convert rectangular to polar, apply these formulas
Note : Rectangular coordinates are the coordinates you were learning since elementary school or middle school.
The first number is x, and the second is y.
So
Since our y coordinate is negative and x coordinate is Positve , on the unit circle, the angle must be in the fourth quadrant.
So the angle must be in between
So our answer is
(6, 11pi/6).
