Prove that `(cos(90^0+theta)sec(theta)"tan"(180^0+theta))/(sec(360^0-theta)sin(180^0-theta)cot(90^0+theta))=1`

Text Solution

Verified by Experts

`L.H.S.=(cos(90^@+theta)sec(-theta)tan(180^@-theta))/(sec(360^@-theta)sin(180^@+theta)cot(90^@-theta))`
`=((-sintheta)(sectheta)(-tantheta))/((sectheta)(-sintheta)(tantheta))=-1=R.H.S.`
