Question 873510: Using fundamental identities to simplify the expression then determine which is NOT equivalent to cotBsecB?
a)secB/tanB
b) 1/cosBtanB
c)1/sinB
d)secB
e)cscB
P.s B equals Beta and the / means the solution is in fraction form.If next to each, then they are being multiplied.

Using fundamental identities to simplify the expression then determine which is NOT equivalent to cotBsecB?
----
Note cot*sec = (cos/sin)(1/cos) = 1/sin = csc
--------------------------------------------
a)secB/tanB = (1/cos)/(sin/cos) = 1/sin = csc
------------------------------------------
b) 1/cosBtanB = 1/[(cos(sin/cos)] = 1/sin = csc
------------------------------------
c)1/sinB = csc
---------------------
d)secB = 1/cos
---------------------
e)cscB
