We have the expressions cosecant theta over sine theta equals cotangent theta, no no, plus cotangent theta over tangent theta.
00:15
And we want to see which one of these is equals to.
00:19
So i'm first going to rewrite this by bringing the cosecant down and making it sine and the cotangent down and bringing it tangent as 1 over sine squared theta plus 1 over tangent squared theta.
00:34
Next i'm going to add the fractions together.
00:36
So this can be tangent squared theta plus sine squared theta over sine squared theta tangent squared theta.
00:46
Now let's look at this denominator.
00:48
I'm going to rewrite that as sine squared theta times sine squared theta over cosine squared theta.
00:57
Now my numerator, i'm going to write that as sine squared theta over cosine squared theta plus sine squared theta.
01:05
Now we have a complex fraction, so i'm going to multiply by each term by cosine squared theta to eliminate that...
