What is the simplified form of 1/(1+cos θ) + 1/(1-cos θ)?
1/(1+cos θ) + 1/(1-cos θ) का सरल रूप क्या है?
Show answer and explanation
Correct Answer
B. 2 / sin²θ
ExplanationStep 1: Add the fractions using common denominator. Step 2: Denominator is 1-cos²θ=sin²θ and numerator is 2 so answer is 2/sin²θ. Step 3: Remember identity 1-cos²θ=sin²θ.
Step 1: Fractions को common denominator पर जोड़ें। Step 2: denominator 1-cos²θ=sin²θ और numerator 2 होगा इसलिए answer 2/sin²θ है। Step 3: 1-cos²θ=sin²θ identity याद रखें।
