#3 tanθ+sinθ/cscθ+cotθ

  • precalculus -

    nice expressions

    what do you want to do with them?

  • precalculus -

    the answer an how to do it

  • precalculus -

    I don't see any questions. How do I provide answers?

    For instance, cscθ-cotθ can be rewritten in many ways, using various combinations of sin,cos, etc. Just plopping a few expressions on the net doesn't elicit any responses. Are these problems in some section of your text? If so, there is usually an instruction on what you are to do with the expressions.
