WebThe first trig equation, cos (α) = \frac {1} {2} 21, gives me α = 60° and α = 300°. The second equation gives me α = 180°. So my complete solution is: α = 60°, 180°, 300° Solve sin (β) = sin (2β) on the interval 0° ≤ β < 360° I can use a double-angle identity on the right-hand side, and rearrange and simplify; then I'll factor: WebThe first solution is 45° more than a multiple of 180°, so (180n)° + 45° should do. The second solution is 30° more than a multiple of 180° and (because of the "plus / minus") also 30° less than that same multiple, so (180n)° ± 30° will cover this part. x = (180n)° ± 30°, (180n)° + 45° for all integers n Content Continues Below Solve dataflow incremental refresh power bi
