To verify the identity start with the more complicated side

To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step.

tan x/sec x = ___/____

What transformation is made in the numerator?

What transformation is made in the denominator?

Solution

tanx/secx=(sinx/cosx)/(1/cosx)=sinx/1

the transformation made to the numerator is sinx

the transformation made to the denominator is 1
