Question

Simplify.
tan^2(x)-sin^2(x)

solomonzelman · Answer

$\LARGE\color{black}{       \tan^2(x)-\sin^2(x)   }$


$\LARGE\color{black}{       \frac{\sin^2(x)}{\cos^2{x}}-\frac{\sin^2(x)}{1}   }$

can you do it from here?

solomonzelman · Answer

you believe it is not going to be simpler once you add the fractions?
Just do what I say step by step.

1)Add the fractions after finding the denominator.  (for now)

solomonzelman · Answer

(multiply top and bottom of the second fraction times  $\large\color{black}{       \cos^2{x}  }$ .

solomonzelman · Answer

$\LARGE\color{black}{       \frac{\sin^2(x)}{\cos^2(x)}-\frac{\sin^2(x)~~  \color{red}{\times\cos^2(x) }  }{1 \color{red}{~~\times \cos^2(x)}}   }$

$\LARGE\color{black}{       \frac{\sin^2(x)}{\cos^2(x)}-\frac{\sin^2(x)~~ {\cos^2(x) }  }{ \cos^2(x)}   }$
