1. cot(x)
2. tan2(x)
3. tan(x)
4. sec2(x)
5. sin(x)
6. csc(x)

Answers:

A. sin(x)
B. 1+tan2(x)
C. sin(x)cos(x)
D. cot(x)
E. 1sin(x)
F. sec2(x)
G. 1sec(x)
H. tan(x)
I. csc2(x)1
J. 1cos2(x)
K. 1sin2(x)
L. 1csc(x)

1. cot(-x)=-cot x that is D .

2. tan²x= sec²x-1

3. tan x= sin x / cos x

4.sec²x=1 + tan²x that is B

5 .sin(-x)=-sin x that is option A

6.csc x =1/sin x that is option E
