Question

prove tan^2theta/sec theta+1=sec theta-1​

Answer 1

Step-by-step explanation:

sec^2theta -than^2 =0

sec^2theta -1=tan^2 theta

given question

tan^2/sectheta +1 =sectheta -1

sec^2-1/sectheta +1 =sectheta -1

(sectheta+1)(sectheta-1)/(sectheta +1)=sectheta -1

sectheta -1 =sectheta -1

Hence proved

Answer 2

Step-by-step explanation:

tan^2 theta/sec theta+1= sec theta-1

tan^2 theta= (sec theta+1)(sec theta-1)

tan^2theta/sectheta+1=sectheta-1

sec^2theta-1/sectheta+1=sectheta-1

sectheta-1=sectheta-1
