    मायूस मत होना यह एक गुनाह होता है;
    मिलता वही है जो किस्मत में लिखा होता है;
    हर चीज़ मिले आसानी से यह ज़रूरी तो नहीं;
    मुश्किलों के दौर में ही तो हिम्मत का पता चलता है।

    cosec a=rt13
    sin a=1/rt13
    cos a=?
    sin^2 a + cos^2 a =1
    (1/rt 13)^2 + cos^2 a =1
    cos^2 a = 1-(1/rt13)^2
    cos a = rt(1-(1/rt13)^2)
    cos a =rt(12/13)
