    If sec@ - tan @ = 1/3 , find the exactly value of sec @ + tan@ . Find also the exact value of sec@ and oftan@ .I tried using (sec@ - tan@)^2 = 1/9But can't get sec@ + tan@...

    Re: Trigon

    To determine (sec(@) + tan(@)), try multiplying both sides by (sec(@) + tan(@)).

    Once you know the value of (sec(@) + tan(@)), then, since you've started with the value of (sec(@) - tan(@)) (it's 1/3), you can then solve simultaneous equations to find the individual values for sec(@) and tan(@).
