Solve the following activity and find the value of `6 tan^(2)theta-6/(cos ^(2) theta)`

Text Solution

Verified by Experts

The correct Answer is:
`6 tan^2 theta - (6)/(cos^2 theta)`
` = 6 [ tan^2 theta - (1)/(cos^2 theta) ]`
`= 6 [ tan^2 theta - sec^2 theta] [1/(cos theta) = sec theta]`
`= 6 [ -1 ]`
= -6
