After a lot of try I got to know that your question is wrong . It is :---
= cos²67+ sin²13
= 1 .......... ( since sin²A + cos²A = 1 )
But if you don't think so then :--
cos²67 sin²13
= ( 1 - sin²13 ) sin²13
But it will not give result . Check the question and inform me . OK!!
ALL THE BEST FOR TOMORROW'S PAPER !!!
HOPE IT GOES WELL AND YOU SCORE EXCELLENT !!!!!
