establish identity

sec 0/1 + sec0 = 1 - cos0/sin^2 0

  • Trig -

    Do you mean sec 0/(1 + sec 0) ?
    On the right side,do you mean
    (1 - cos 0)/sin^2 0?

    You need to use parentheses to make your equations unambiguous.

    How would you establish this identity: (1+sec(beta))/(sec(beta))=(sin^2(beta))/(1-cos(beta)) on the right, sin^2 = 1-cos^2, that factor to 1-cos * `1+cos, then the denominator makes the entire right side 1+cosB which is 1+1/sec which …
