document.write( "\n" );
document.write( "At first since we are dealing with sec t I took the trig functions formulas which are: Sin = y/r csc = r/y, cos = x/r sec = r/x, and tan = y/x cot = x/y I took sec = r/x and figured there would be a 1 under the -4 to hold the place so r = -4, x = 1 and to find y I took x^2 + y^2 = r^2 and got the square root of -17. but square roots cant be negative so i'm not sure if i am right or not. Can you help me? Also, I wasn't aloud to use a calculator for this problem. \n" );
