Pls help me with this question........ |

Answer» (1+tan^2 θ) cot θ/ cosec^2 θ = sec^2 θ . cot θ/ cosec^2 θ ( we know, sec^2 θ - tan^2 θ = 1) sec^2 θ = 1+ tan^2 θ In next step we convert sec^2 into 1/cos^2, cot into cos/SIN and cosec^2 into 1/ sin^2 respectively.... Hence we get, [1/cos^2 θ × cos θ/sin θ]/ 1/ sin^2 θ = 1/ sin θ . cos θ × sin^2 θ = sin θ/ cos θ = tan θ Hope it will help you ✌️ |
