Is the answer 9cosec^2 theta - 35cos^2 theta? If yes , I would upload the answer as soon as I can

yoshitha123: yes

TheMandy: Given : 6x = sec theta , so x = sec theta/ 6.Now in 9(x^2 - 1/x), substituting value of x.In few steps you would get sec^2 theta -36 , there break -36 into -1 -35.Using identity, convert sec^2 - 1 - 35 into tan^2 theta -35. So the final equation is 9(tan^2 theta -35/sec^2 theta).Divide tan^2 theta - 35 by sec^2 theta . Now you get the answer as 9(cosec^2 theta -35cos^2 theta)!. PS.I'm not able to upload the pic of the answer.If you liked my answer pls rate it as 'brainliest answer'
