think of a unit circle. now locate the -ninety perspective. sin is the dimensions of the radius interior the y direction, and cos is the dimensions of the radius interior the x direction. now use the definitions of something of the trigonometric purposes in terms of sine and cosine to locate something. yahoo solutions won't be able to do your homework for you.

csc t = 1/ sin t = 5/sqrt(23)
sec t = 1/ cos t = 5/ sqrt(2)
tan t = sint t / cos t = sqrt(23) / sqrt(2)
