Are you studying for a trig test?
Where is your effort?
Why do you not try to solve each question and show your work?
Then we can help you better.
I would like to know if you are preparing for a math state test.
I have been showing my work in my book but not for these questions b/c I have no clue as to how to solve them its just I need them to be checked and its just too time consuming to post the work on the computer. I really appreciate everyone's help.
I am willing to do one just to show you how. Express all functions as sin and cos, for example tan = sin/cos and then remember that sin^2 + cos^2 = 1
4)Which expression is not equivalent to 1?
I don't know
A)--> sin^2 T ( 1 + cos^2 T/sin^2T)
= sin^2T+ cos^2 T = 1
B) --> sin^2 T/(1-cos T) - 1
= sin^2 T (1+cos T)/(1-cos^2T) - 1
= 1 + cos T - 1
this is not 1
C) --> 1/cos^2 T + + sin^2/cos^2 T
= (1+sin^2 T)/cos^2T
that is not 1 either, but I bet you have a typo in the original sign
D) --> cot^2thetasin^2theta/cos^2theta
= (cos^2 T sin^2T)/(sin^2 T cos^2 T)
