નીચેનું સમીકરણ ઉકેલો :
2 space cos space 2 straight theta space plus space square root of 2 space equals space 0


therefore space cos space 2 straight theta space equals space minus fraction numerator 1 over denominator square root of 2 end fraction space equals space cos space open parentheses straight pi space minus space straight pi over 4 close parentheses space equals space cos space open parentheses fraction numerator 3 straight pi over denominator 4 end fraction close parentheses

therefore space cos space 2 straight theta space equals space cos space open parentheses fraction numerator 3 straight pi over denominator 4 end fraction close parentheses

therefore space 2 straight theta space equals space 2 kπ space plus-or-minus space fraction numerator 3 straight pi over denominator 4 end fraction comma space straight k space element of space straight Z

therefore space straight theta space equals space kπ space plus-or-minus space fraction numerator 3 straight pi over denominator 8 end fraction space comma space straight k space element of space straight Z

therefore space ઉક ે લગણ space colon space open curly brackets kπ space plus-or-minus space fraction numerator 3 straight pi over denominator 8 end fraction space left enclose space straight k space element of space straight z end enclose close curly brackets
