    Verify the following identities, show all work

    secx(1-sin^2x)=cosx

    tanx + cotx=secxcscx

    cotx/cosx=cscx

    csc^2x(1-cos^2x)=1

    cosxcotx + sinx=cscx

    1) secx(1-sin^2x)=cosx
    (1-sin^2x) is Cos^2x

    so secx Cos^2x

    Secx = 1/cosx

    rewriting , cos^2x/cosx = cosx

    2)tanx + cotx=secxcscx

    tanx ...
