Find the value(s) of c guaranteed by rolle's theorem for f(x) = x sinx on the interval
[-3,3]. i found the derivatives but i dont understand how to fibd the zeros

The value of c is 0,-2.194 and 2.194 in the interval (-3,3).

Step-by-step explanation:

To find the value of c for a given function using Rolle's Theorem we have to find the first derivative of the function and then equate it to zero.

These solutions of x are the values of c.

f(x) = x sin(x)

= xcosx + sinx

xcosx + sinx = 0

x = -tanx

Using the graphical method we can see that 0,-2.194 and 2.194 is a solution of the equation.There are infinitely many solutions but in the interval (-3,3) there is only 3 solution.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
