slavikrds [6]

Answer:

The correct answer is yes its true.

Step-by-step explanation:

Let ABCD is a rectangle which means rectangle have opposite sides of same length : AB = CD and AD = BC.

It is given that O is the point of intersection of the diagonals that means O is mid point of AC and DB,

I plugged in 4 for the derivative function but I’m getting the wrong answer?
Georgia [21]

Answer:

8.6615988

Step-by-step explanation:

f(x) = 3 sin (x) / ( 1 + cos x)

To find the derivative   bottom * d/ dx top  - top d/dx bottom  all over the bottom squared

d/dx = 3 ( ( 1 + cos x)  cos x - sin x( - sin x))   / ( 1 + cos x) ^2

         = 3 ( cos x + cos ^2 x + sin ^2 x)   / ( 1 + cos x) ^2

         = 3 ( 1 + cos  x) /  ( 1 + cos x) ^2

         = 3 / ( 1 + cos x)

Let x = 4

3  /  ( 1 + cos 4)

Assuming x is in radians
