Hi Everyone,
I know that we need to know the relationships between sin, cos (vice versa), tan and sec (vice versa). But do we need to know about cot and cosec ???
They are not included in the exercises I have done, so I assume that cot and cosec are not required. However, cot was in my Trials....so I am nervous....
Could someone put my mind at rest??
Thanks !!
