Question

Oblicz : sin(x/4-3/2) = 1/2

Answer 1

sin(x/4-3/2) = 1/2

sin(x/4-3/2) = sin30*

x/4 - 3/2 = 30* + 2kπ                    lub   x/4 - 3/2 = (180* - 30*) + 2kπ

x/4 = 30* + 3/2 + 2kπ       /*4        lub   x/4 = 150* + 3/2 + 2kπ     /*4

x = 120* + 6 + 8kπ                                  x = 600* +6 + 8kπ
