Homework Statement
Solve cotxcsc2x=2cotx
Homework Equations
The Attempt at a Solution
cotx(csc2-2)
cotx = 0
x = no solution
x = sin-1(1/√2)
or
x = sin-1(-1/√2)
I come up with the solutions x = { π/4, 3π/4, 5π/4, 7π/4}
However the solutions are telling me that x can also be equal to π/2 and 3π/2 although I have no idea how this could be?
