tan²alpha tan²beta+tan²beta tan²gamma+tan²alpha tan²gamma+2 tan²alpha tan²beta tan²gamma = 1

TO find the value of sin²alpha + sin²beta + sin²gamma

tan squared straight alpha space tan squared straight beta space plus space tan squared straight beta space tan squared straight gamma space plus space tan squared straight gamma space tan squared straight alpha space plus space 2 space tan squared straight alpha space tan squared straight beta space tan squared straight gamma space equals space 1 rightwards double arrow space sin squared straight alpha space sin squared straight beta space cos squared straight gamma space plus space cos squared straight alpha space sin squared straight beta space sin squared straight gamma space plus space sin squared straight gamma space sin squared straight alpha space cos squared straight beta space plus space 2 space sin squared straight alpha space sin squared straight beta space sin squared straight gamma space equals space cos squared straight alpha space cos squared straight beta space cos squared straight gamma rightwards double arrow space sin squared straight alpha space sin squared straight beta space open parentheses 1 minus sin squared straight gamma close parentheses space plus space open parentheses 1 minus sin squared straight alpha close parentheses space sin squared straight beta space sin squared straight gamma space plus space sin squared straight gamma space sin squared straight alpha space open parentheses 1 minus sin squared straight beta close parentheses space plus space 2 space sin squared straight alpha space sin squared straight beta space sin squared straight gamma space equals space cos squared straight alpha space cos squared straight beta space cos squared straight gamma rightwards double arrow sin squared straight alpha space sin squared straight beta space plus space sin squared straight beta space sin squared straight gamma space plus space sin squared straight gamma space sin squared straight alpha space minus space 3 space sin squared straight alpha space sin squared straight beta space sin squared straight gamma space plus space plus space 2 space sin squared straight alpha space sin squared straight beta space sin squared straight gamma equals open parentheses 1 minus sin squared straight alpha close parentheses open parentheses 1 minus sin squared straight beta close parentheses open parentheses 1 minus sin squared straight gamma close parentheses rightwards double arrow sin squared straight alpha space sin squared straight beta space plus space sin squared straight beta space sin squared straight gamma space plus space sin squared straight gamma space sin squared straight alpha space minus space sin squared straight alpha space sin squared straight beta space sin squared straight gamma space equals space space space space space 1 minus sin squared straight alpha minus sin squared straight beta minus sin squared straight gamma plus sin squared straight alpha space sin squared straight beta space plus space sin squared straight beta space sin squared straight gamma space plus space sin squared straight gamma space sin squared straight alpha minus sin squared straight alpha space sin squared straight beta space sin squared straight gamma rightwards double arrow 0 equals space 1 minus sin squared straight alpha minus sin squared straight beta minus sin squared straight gamma rightwards double arrow space sin squared straight alpha plus sin squared straight beta plus sin squared straight gamma equals 1
