Combine the two terms in the numerator by getting common denominators. Do not apply identities in the

numerator. Retype the denominator from the previous step.

Choose the correct final steps:

$=($sin$^(2)$x$+$cos$^(2)$x$)/($cosxsinx$)*($sinx$)/(1)=(1)/($cosx$)=$cscx

$=($sin$^(2)$x$+$cos$^(2)$x$)/($cosxsinx$)*($cosx$)/(1)=(1)/($sinx$)=$cscx

$=($sin$^(2)$x$-$cos$^(2)$x$)/($cosxsinx$)*($sinx$)/(1)=(1)/($cosx$)=$cscx

$=($sin$^(2)$x$-$cos$^(2)$x$)/($cosxsinx$)*(1)/($cosx$)=(1)/($cosx$)=$secx

$=($sin$^(2)$x$+$cos$^(2)$x$)/($cosxsinx$)*(1)/($cosx$)=(1)/($sinx$)=$cscx

$=($sin$^(2)$x$-$cos$^(2)$x$)/($cosxsinx$)*($cosx$)/(1)=(1)/($sinx$)=$cscx
