SOLUTION: Find all real numbers that satisfy the equation:
cos(2pix) = 0
Here is my solution, but I don't know how to get the solution set:
2pix = pi/2 + 2kpi or 2pix = 3pi/2 + 2kpi

x = 1/4 + k or x = 3/4 + k Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Find all real numbers that satisfy the equation:
cos(2πx) = 0
2πx=π/2+2πk and 3π/2+2πk, k=integer
two equations:
2πx=π/2+2πk
4πx=π+4πk
4x=(1+4k) , k=integer
..
2πx=3π/2+2πk
4πx=3π+4πk
4x=3+4k , k=integer
solution:, and , k=integer
