1)  +  = 2 sec t	1)  _____________

2)   =  csc x cot x	2)  _____________

3)  = 	3)  _____________

4)  +  = -2 csc x	4)  _____________

5)   = 	5)  _____________

1)  +  =   =  =  = 2 sec t.
2)   =   =  =  ∙  =  = csc x cot x
3)  = =  =  
4)  +  =   =  =  =  = -  = -  ∙  = -  = - 2 csc θ
5)   = x + 2 sec x tan x + x =  +  +   =  =   =  =
