Prove that... √sec²Ø + cosec²Ø = tanØ + CotØ |
|
Answer» ?? Sorry...last se 2nd wali ye hogi...√(tan theta +cot theta)2 LHS - √sec2theta + cosec2theta => √(1+tan2theta)+(1+cot2theta) => √(tan2theta + cot2theta + 2) => √(tan2theta + cot2theta + 2×tan theta × 1/tan theta) => √(tan2theta + cot2theta + 2×tan theta × cot theta) => √(tan2theta + cot2theta)2 => tan theta + cot theta Now, LHS = RHS...So, it\'s prove.. |
