Question

how do i find the real solutions of [ cot theta=0 ]

Answer 1

at 0? maybe im not quite sure

Answer 2

thats all it gives me

Answer 3

cotangent is cosine/sine
If the cosine is 0, the fraction is 0 so find the values for which the cosine is 0

Answer 4

ok thank you. it would be pi/2 in the interval 0,2pi

Answer 5

And 3pi/2

Answer 6

ahhh yeah 3pi/2. thank you

Answer 7

yw

Answer 8

what about cot^2x = 3

Answer 9

i figure it to be cot x = radical 3 im not sure where to go from there

Answer 10

\[\cot ^2x=3\]
\[\cot x=\pm \sqrt{3}\]
\[\tan x=\frac{1}{\cot x}=\pm \frac{1}{\sqrt{3}}=\pm \frac{\sqrt{3}}{3}\]

Answer 11

So find the values of x that have that tangent

Answer 12

30 or pi/6
