In my work they are asking for the exact values of in all forms: Sin, Cos, Tan and recipricols by using double angle formula's. Sin and Cos of make sense but i have a query involving Tan and Cotan.
i have figured out that
i have also figured out that
How would i go about figuring out , Using the respective double angle formula didn't work so now i am stumped. Also i don't know at which point i should switch the numerator and denominator for Recipricol functions
and times by the conjugate to get the answer?
any help would greatly boost my confidence
