How do you simplify tan^2y/secydiv(3tan^3y)/secy?

1 Answer

(tan^2y/secy)xx((secy)/(3tan^3y))=1/(3tany)=coty/3

Explanation:

Remember that when dividing fractions, it's the same as multiplying by the inverse. And so this:

(tan^2y/secy)-:((3tan^3y)/secy) becomes

(tan^2y/secy)xx((secy)/(3tan^3y))

cancel out terms to get

(tan^2y/secy)xx((secy)/(3tan^3y))=1/(3tany)=coty/3
