Question

prove that . Sec²theta -1 / tan²theta = 1​

Answer 1

Answer:

Step-by-step explanation:

Given,

sec^2∅-1/tan^2∅=1

But we know that sec^2∅-tan^2∅=1

sec^2∅-1=tan^2∅

By substituting, We get,

tan^2∅ /tan^2∅ =1

Hence,sec^2∅-1/tan^2∅=1

Its proved..

Answer 2

Answer:

1

Step-by-step explanation:

sec2theta=1+tan2theta

1+tan2theta-1/tan2theta

     =1
