Question

if tan theta+sec theta=2/3 then tan theta-sec theta= what​

Answer 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Taking x instead of theta

We have secx + tanx = 2/3-------- eqn 1

We know that sec² x - tan² x = 1

So,

(Secx - tanx)(secx + tanx)= 1

(Secx-tanx)2/3=1

Secx-tanx = 3/2-----------eqn 2

Adding eqn 1 and 2 we get

2secx = 3/2+2/3

2Secx=13/6

Secx= 13/12 answer
