Solve the equation (use n as an integer constant): 3 cot^2(x) − 1 = 0.

x = (smaller value)
x = (larger value)

The following are the answers to the questions presented:

x = -π/3 (smaller value)

x = π/3 (larger value)

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
