How to simplify sin 4x
Web2. Rearrange both: sin^2x=1-cos^2x and cos^2x=cos2x+sin^2x 3. Substitute cos2x+sin^2x into sin^2x=1-cos^2x for cos^2x 4. Expand: sin^2x=1-cos2x-sin^2x 5. Add sin^2x to both … Web4 x = π − x 4 x = x + 2 π 4 x = 3 π − x for three different values of x, and those will be your solutions. (Be sure that the domain of solutions really is 0 < x < π, for otherwise 0 and π are also solutions.) See if you can apply the same kind of thinking for the second problem.
