Derive cos2x=1-(tan)2x/1+(tan)2x |
|
Answer» LHS, We have, cos 2x = cos²x - sin²x = (cos²x - sin²x) / 1 = (cos²x - sin²x) / (cos²x + sin²x) = {cos²x[1-(sin² X/cos² x)]} / {cos²x[1+(sin²x/cos²x)]} ⇒ cos2x = (1 - tan²x) / (1 + tan²x)= RHS Hence Proved !! |

Answer» here is your answer ✨❤️✔️⬇️ Answer: ok I will do quick✔️....XD We know that the LARGEST 3 digit number is 999. So we will find out the square root of 999 by long division METHOD and check WHETHER it is a perfect square or not.✨ 8MathsSquareandSquareRoots✨ Here we can see that 999 is not a perfect square as it leaves 38 as remainder.✨ So if 38 will be addede to 999 then it will become a 4 digit number. THEREFORE to find the largest 3 digit perfect square we will SUBTRACT 38 from 999.✨ 999 - 38 = 961.✨ Hence 961 isthe largest 3 digit perfect square whose square root is 31.⬇️ I gave an example so that it can help you to understand better✔️⬇️✨❤️ mark as brainliest answer ✔️ |

(a-3) x² + 4 (a-3) x+4 =0 has equal roots. Find the value of a |
Answer» Answer :a = 19 Note:★ The possible values of the variable which satisfy the equation are called its roots or solutions . ★ A QUADRATIC equation can have atmost two roots . ★ The general form of a quadratic equation is given as ; Ax² + Bx + C = 0 ★ If α and ß are the roots of the quadratic equation Ax² + Bx + C = 0 , then ; • Sum of roots , (α + ß) = -B/A • PRODUCT of roots , (αß) = C/A ★ If α and ß are the roots of a quadratic equation , then that quadratic equation is given as : k•[ x² - (α + ß)x + αß ] = 0 , k ≠ 0. ★ The DISCRIMINANT , D of the quadratic equation Ax² + Bx + C = 0 is given by ; D = B² - 4AC ★ If D = 0 , then the roots are real and equal . ★ If D > 0 , then the roots are real and distinct . ★ If D < 0 , then the roots are unreal (imaginary) . Solution :Here , The given quadratic equation is ; (a-3)x² + 4(a-3)x + 4 = 0 Now , COMPARING the given quadratic equation with the general quadratic equation Ax² + Bx + C = 0 , we have ; A = (a - 3) B = (a - 3) C = 4 Now , The discriminant of the given quadratic equation will be given as ; => D = B² - 4AC => D = (a - 3)² - 4×(a - 3)×4 => D = (a - 3)² - 16(a - 3) => D = (a - 3)(a - 3 - 16) => D = (a - 3)(a - 19) Now , The given quadratic equation will have equal roots if its discriminant is zero . Thus , => D = 0 => (a - 3)(a - 19) = 0 => a = 3 , 19 Here , a = 3 is rejected value , because if a = 3 , the given equation will no more be a quadratic equation . Thus , a = 19 is appropriate value . Hence ,Required value of a is 19 . |
