Question

determine the answer that established the identity.
tan theta/sin theta sec theta =

nnesha · Answer

$$\huge\rm \frac{ \tan \theta }{ \sin \theta \sec \theta   }$$ like this ?

helenredk · Answer

yes

nnesha · Answer

alright. rewrite tan and sec in terms of sin,cos

helenredk · Answer

i hate this stuff.  its confusing

nnesha · Answer

what's the inverse of tan ??
what's the definition of cos, sin tan ?

nnesha · Answer

you should bookmark this website for trig ratios and identity http://www.analyzemath.com/trigonometry/trigonometric_formulas.html look at number 5 (Relations Between Trigonometric Functions) )

tan theta = sinx/cosx
and secx=1/cosx 
so  $$\large\rm \frac{\frac{\sin \theta}{\cos \theta}}{\sin \theta \cdot \frac{1}{\cos \theta}}$$
now you can change division to multiplication 
multiply tthe top fraction with the reciprocal of the bottom fraction
