    cot tan help .

    Hello! I'm new to the forum, and really really happy I found it!
    I couldn't find an intro section, so thought I'd say hello here .

    Now.
    I understand if someone asks, what is the sin(36)?
    But if I have a problem
    cot(6836') what does that mean? Does it mean the cot of 68.36? Or the supplementary of 68, and the complimentary of 36? And how would I solve for it? By taking the tan of the supplementary and complimentary?

    Any help is greatly appreciated! Thank you!

    This is a notation for degree's minutes and seconds

    a minute (')is 1/60 of a degree and a second ('') is 1/60 of a minute.

    So you have 68 degrees and 36 minutes this is the same as

    68+\frac{36}{60}=68.6^\circ

    Oh! Now I understand! Thank you. And the cot of 68.6 would be the tan of the reference angle?

    Edit - I got it now, it's 1/tan(68.6) !
