1.	If sin theta +tan theta =m and sin theta - tan theta =n. Prove that m^2 - n ^2 =4 under root "mn"
Answer» Thank you for answers lHS=(sin+tan)^2-(sin^2-tan^2). A. (Sin^2+tan^2+2sintan)-(sin^2+tan^2-2sintan). B. Sin^2+tan^2+2sintan-sin^2-tan^2+2sintan. C. 4sintan D. RHS=4√(sin+tan)(sin-tan). A. =4√sin^2-tan^2. S. =4√sin^2-sin^2/cos^2. R. =4√sin^2cos^2-sin^2. A. ------------------------------. F. Cos^2. A. =4√sin^2(cos^2-1). T. ---------------------. =4tan*sin. I. Cos^2 (TanA +sinA) ^2-2ho)(tanA-sinA)^2=√(tanA+sinA)(tanA-sinA)
