Y = ln {[sin(x)]^2}
use the chain rule
y' = 1 /[sin(x)]^2 * 2sin(x)*cos(x) = 2cos(x) / sin(x) = 2 cot(x)
Answer: 2 cot(x)
There are no numbers without decimals which multiply to 78 and add up to 17.
The number of numbers which are a units away from 0 if a>0 is; 2 numbers.
<h3>
Distance between numbers on the number line</h3>
by convention, the distance between two numbers on the number line is usually a positive number.
On this note, since the required numbers are a units away from zero, it follows that;
OR
On this note, only 2 numbers are a units away from zero according to the given condition.

Radian measure is given by dividing the length of an arc by the radius of a given circle. Such that an arc that subtends an angle of 1 radian to the center of a circle is equivalent to the radius of the circle.
Therefore; θ = s/r where θ is the angle subtended in radians, s is the length of the arc and r is the radius of the circle.
Hence; r = s/θ
= 12π ÷ (4π/7)
= 12 × (7/4)
= 21 inches
