Questions & Step-by-Step Solutions

What are the solutions of the equation sin(2x) = 0 in the interval [0, 2π]?
  • Step 1: Understand the equation sin(2x) = 0. This means we need to find the values of 2x where the sine function equals zero.
  • Step 2: Recall that sine equals zero at integer multiples of π. So, we can write the equation as 2x = nπ, where n is any integer.
  • Step 3: Solve for x by dividing both sides of the equation by 2: x = nπ/2.
  • Step 4: Determine the values of n that keep x within the interval [0, 2π].
  • Step 5: For n = 0: x = 0/2 = 0.
  • Step 6: For n = 1: x = 1π/2 = π/2 (not a solution).
  • Step 7: For n = 2: x = 2π/2 = π.
  • Step 8: For n = 3: x = 3π/2 (not a solution).
  • Step 9: For n = 4: x = 4π/2 = 2π.
  • Step 10: Collect the valid solutions: x = 0, π, and 2π.
