Consider the following points on the graph of y=sin(x)

 

https://docs.google.com/document/d/1aHUVqjrIYnITSuw5MIPSvx_XD-0UItgdCAeLTALxebo/edit?usp=sharing

 

Say that the terminal points of angles a and b are as follows:

Terminal point of a = (c1, c2)

Terminal point of b = (d1, d2)

 

Enter c1, c2, d1, d2 in that order.

 

Thanks!

 

(I've shown the points of y=sin(x) in the google doc link above)

sin (a)  = 3/5

 

(c1,c2) = ( sqrt (5^2 - 3^2), 3)  = sqrt (16), 3)  =   (4,3)

 

sin (a) =  4/5

 

(d1, d2)  = ( sqrt (5^2 - 4^2) , 4)  = (sqrt (9) , 4)  = (3, 4)
