Question

Simplify the expression.
sec x/tan x

Answer 1

Answer:

Option b

Step-by-step explanation:

We know that, by definition:

$secx = \frac{1}{cosx}$

We also know that:

$tanx = \frac{sinx}{cosx}$

Applying these identities we can simplify the given expression

$\frac{secx}{tanx} = \frac{\frac{1}{cosx}}{\frac{sinx}{cosx}}\\\\\frac{secx}{tanx} = \frac{cosx}{sinxcosx}\\\\\frac{secx}{tanx} = \frac{1}{sinx}$

We know that, by definition:

$\frac{1}{sinx} = cscx$
