Text Solution

Verified by Experts

Given,
`(1 + tantheta + sectheta)(1+ cottheta - cosectheta)`
`=(1 + (sintheta)/(costheta) + 1/(costheta))(1+ (costheta)/(sintheta) - 1/(sintheta))`
`=((costheta+sintheta+1)(sintheta+costheta−1))/(costheta.sintheta)`
`=((costheta+sintheta)^2−1)/(costhetasintheta)`
`=(cos^2theta+sin^2theta+2costhetasintheta−1)/(costhetasintheta)` ...
