Question 192090: **just for starters in the equation that i am about to show you, i am using the 0 symbol as the theta/angle symbol (also in question A))**
For sin0+cos0cot0=csc0, do the following
A) Show that the equation is true when 0= thirty degrees
B) Prove the equation algebraically
C) State any restrictios that are in the equation

---------------
Since there's only one angle involved, just leave it out.
B)
sin + cos*cot = csc
sin + cos*cos/sin = 1/sin
sin^2 + cos^2 = 1 An identity, so it's true.
--------------------
A)
Since it's true in general, it's true for 30 degs.
--------------
C)
At n*pi (or n*180 degs) both the cot and the csc are undefined.
