Answer» -step EXPLANATION:We will do it step by step.We KNOW thatsecA=1/cosAtanA=sinA/cosAcotA=cosA/sinATaking L.H.SStep 1.put these formulas in question ,we get(1/cosA)/[(sinA/cosA)+(cosA/sinA)]Step 2. After taking L.C.M we getcosAsinA/cosA(sin^2A+cos^2A)sinA/sin^2A+cos^2A——(1)Step 3. We know thatsin^2A+cos^2A=1——(2)Step 4. Put value from eq. (2)to eq.(1) ,we getsinAWe can SEE thatL.H.S = R.H.Smake me as BRAINLIEST |
