Verify that the equation is an identity.
secx-cosx=sinxtanxTo 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.
secx-cosx=(1)/(cosx)-cosx
=
=(sin^(2)x)/(cosx)
=
=sinxtanx
?Use a common denominator to perform the subtraction.
