Question

which expression is equivalent to cot t sec t?
A. csc t
B. sin t
C. tan t
D. sin^2 t
E. csc^2 t

Answer 1

write sec and cot in terms of sin or cosine :-)
sec = ?
cot = ?

Answer 2

what?

Answer 3

what's the definition of sec
like tan = sin/cos
sin = 1/csc
sec = ?

Answer 4

idk

Answer 5

alright that's the first thing to know for trig \[\tan = \frac{ \sin }{ \cos }~~~~~\cot=\frac{ \cos }{ \sin } ~~~\sin=\frac{ 1 }{ \csc}~~~\cos=\frac{ 1 }{ \sec } \]
tan is reciprocal of cos
and same with sin and cos
so
csc = 1/sin
sec = ?
