Question

Which value is a solution for the equation cot(x/2)=1?

Please explain. Thank you!

Answer 1

do you know how to solve cot(theta)=1 ?

Answer 2

or you can plug and check

Answer 3

I think I figured it out is this right @freckles

cot(x/2) = 1

1/tan(x/2) = 1

tan(x/2) = 1

x/2 = pi/4

x = pi/2 , 5pi/2

C. 5π/2is the answer

Answer 4

cool
stuff

Answer 5

cot(x/2)=1 when x/2=pi/4 or 5pi/4 we can also include a whole bunch of other values
so x=2pi/4 or 2(5pi/4)
so reducing gives x=pi/2 or 5pi/2
