Question

cos square teta - sec square teta =​

Answer 1

Answer:

The minimum value of cos2θ+sec2θ is

We know, arithmatic mean of two terms is always greater than or equal to their geometric mean. So, minimum value of cos2θ+sec2θ is 2.

Answer 2

Answer:

the minimum values of cos^2teta+sec^2teta is arthemic mean of two terms is always greater than or equal to their geometric mean so minimum value of cos^2 teta+sec^2teta is 2
