Answer:

I substitued theta as A. You can write theta instead of A.

Step-by-step explanation:

f(A)= tanA+secA

or, f(A)=sinA/cosA + 1/cosA

or, f(A)=(1+sinA)/cosA

or,f(A)=(1+sinA)(1-sinA)/cosA(1-sinA)

or,f(A)=(1²-sin²A)/cosA(1-sinA)

or,f(A)=cos²A/cosA(1-sinA)

or, f(A)=cosA/(1-sinA)

or, f(A) =g(A)

f(A)=g(A) proved..
