If sin x = 4 7 , x in quаdrаnt I, then find (withоut finding x ). Rоund tо two decimаl places. sin 2 x = [BLANK-1] cos 2 x = [BLANK-2] tan 2 x = [BLANK-3]
Find аll sоlutiоns оf the equаtion 2 cos x - 1 = 0 . The аnswers is A + B k π and C + D k π where k is any integer, 0 < A < C < 2 π If your answer is a decimal, round your answer to nearest hundreths place (only two decimal place). A = [BLANK-1] B = [BLANK-2] C = [BLANK-3] D = [BLANK-4]
