Question

a)Find an angle  with  that has the same:

Sine as :  =    radians

Cosine as :  =    radians

b)Find an angle  

Sine function value as 

θ=  radians

Cosine function value as 

radians

Answer 1

Sin pi/6 would be in Quadrant 2 Where sin is also +. This would be 5pi/6

For cosine pi/6 Angle would be in quadrant 4 where cos is also + This would be 11pi/6

7pi/6 is in quadrant 3 where both sin and cosine are - so for sin 7pi/6 our angle would be in quadrant 4 where sine is also negative. This would be 11pi/6

For cos 7pi/6 we need an angle in quadrant 2 where cosine is also negative

This would be 5p/6
