Question

Prove this equation ​

Answer 1

Step-by-step explanation:

(sinA+cosA)/(sinA-cosA) +(sinA-cosA)/(sinA+cosA)

= after rationalisation

(sinA+cosA)^2/sin^A-cos^2A +

(sinA-cosA)^2/sin^2A-cos^2A

(sin^A+cos^2A+2cosAsinA +sin^A+cos^2A-2sinAcosA)/(sin^2A-cos^A)

(2 -2sinAcosA +2sinAcosA)/(sin^2A-cos^2A)

2/sin^2A-cos^2A

2/sin^2A-(1-sin^2A)

2/sin^2A-1+sin^2A

= 2/2sin^2A-1

hence proved !
