Question

value of tan^2thita.sec^2thita(cot^2 thita-cos^2 thita)=
​

Answer 1

Answer:

1

Step-by-step explanation:

tan^2theta sec^2theta(cot^2 theta -cos^2 theta)

=( tan^2 theta sec^2 theta cot^2 theta) - (tan^2 theta sec^2 theta cos^2 theta)

= (tan^2theta sec^2 theta 1/tan^2 theta) -( tan^2 theta 1/cos^2theta cos^2 theta)

= sec^2 theta - tan^2 theta

= 1
