Question

Proving trig equations?

Answer 1

@satellite73

Answer 2

i can probably do this one \[\bf {\dfrac{sin~x}{1~-~cos~x}+\dfrac{sin~x}{1~+~cos~x}~=~2~csc~x}\\\] since i think all you need to do is add

Answer 3

\[\frac{b}{1-a}+\frac{b}{1+a}=\frac{b(1+a)+b(1-a)}{1-a^2}\]

Answer 4

Messed up typing them out
\(\bf cot~x~sec^4x~=~cot~x~+~2~tan~x~+~tan^3x\\\)
\(\bf (sin~x)(tan~x~cos~x~-~cot~x~cos~x)~=~1~-~2~cos^2x\\\)
\(\bf 1~+~sec^2x~sin^2x~=~sec^2x\\\)
\(\bf -~tan^2x~+~sec^2x~=~1\)

Answer 5

how many you got?

Answer 6

5 total, should I post them all as separate questions

Answer 7

probably be best
you can copy and paste from here so you don't have to type them all again
