Step-by-step explanation:
sin4Acosec2A+cos4Asec2A=sin2Asin4A+cos2Acos4A=sin2A+cos2A=1
Answer:
Step-by-step explanation:
a. (-6/2)*(1/3)*(36/2)=-18; b. (125/100)*(-2/2)
Answer:
(4, - 6 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , thus
(6, 4 ) → (4, - 6 )
