Find the value of the sine of the smallest angle in standard

Find the value of the sine of the smallest angle in standard position with the point (-12, 5) on its terminal side. Give as four decimals. 0.3846 -0.4167 0.4167 2.6000 it is possible that there is an angle where secA

Solution

1) (-12 , 5)

sin= 5/sqrt(12^2 +5^2) = 5/13 =0.3846

2) secA < sinA

1/cosA <sinA

1< sin2A/2

2< sin2A

Not possible

False

3) cost67 = 1/tan67 = 1/2.35585 = 0.42447 = 0.4245
