Question 1202973
.


You can easily check it graphically / visually on your own.


Go to web-site www.desmos.com/calculator.


Print there the expression of the left side - you will see the plot of the left side function.


In the next line,  print expression for the right side,  which is a constant  "1".


Look at the interval  [0,2pi)  and count how many intersection points do you see there.
