Q. Find an angle θ coterminal to 1043∘, where 0∘≤θ<360∘.Answer:
Divide by 360: To find an angle coterminal to 1043∘ that lies between 0∘ and 360∘, we need to subtract or add multiples of 360∘ until the angle is within the desired range.
Subtract full rotations: First, we determine how many full rotations of 360° are contained in 1043°. We do this by dividing 1043 by 360. 1043÷360≈2.8972This means that 1043° contains 2 full rotations plus some extra degrees.
Calculate coterminal angle: Since we are only interested in the extra degrees, we subtract the full rotations 2×360∘ from 1043∘.1043∘−(2×360∘)=1043∘−720∘=323∘
Calculate coterminal angle: Since we are only interested in the extra degrees, we subtract the full rotations 2×360∘ from 1043∘.1043∘−(2×360∘)=1043∘−720∘=323∘The result, 323∘, is the coterminal angle to 1043∘ that lies between 0∘ and 360∘.
