sin(t)=7/√50

cos(t)=-√50

tan(t)=7

csc(t)=√50/7

sec(t)=√50

The book gives the following answers:

sin(t)=-7√2/10

cos(t)=-√2/10

tan(t)=7

csc(t)=-5√2/7

cot(t)=1/7

I can't quite figure out how I got the answers I did (and that they are so different from the answers shown in the book). Can anyone help me clear this up?
