Simplifying Trigonometric expressions

Click For Summary
SUMMARY

The discussion focuses on simplifying the trigonometric expression \(\frac{6\cos\vartheta}{2\sin\vartheta-3\cos\vartheta}\). Participants suggest using the double angle formulas, which may lead to an expression like \(\frac{6\cos\theta}{2\cos 2\theta - \sin\theta}\). Another approach involves rewriting \(\sin\theta\) as \(\tan\theta \cos\theta\) to eliminate cosine from the denominator. Ultimately, the consensus is that further simplification is limited.

Homework Statement



Hey guys, having a trig brain fart here, can you point me in the direction of simplifying:

[tex]\frac{6cos\vartheta}{2sin\vartheta-3cos\vartheta}[/tex]

or is it as simplified as it gets? \

Homework Equations



Thought about using double angle formula


The Attempt at a Solution


Just a point in the right direction would be helpful, i.e. what identity to use if the expression can be simplified

You could try double angle formulas, but then you will probably end up with
[tex]\frac{6 \cos\theta}{2 \cos 2\theta - \sin\theta}[/tex]
or something like that.

You could rewrite [itex]\sin\theta = \tan\theta \cos\theta[/itex] and get rid of the cosine.

Other than that, I don't think there is much simplification possible.
