Study Notes
Relation R and Properties
- A relation R is defined for x, y ∈ℝ, where xRy if and only if 2x - 2y + 3√5 is an irrational number
- The relation R is not symmetric, transitive, or reflexive
Integration
- ∫(x² - 6x + 9)⁻¹/² dx = √(x² - 6x + 4) / (x - 3) + C
- Another correct integral is 2√(x² - 6x + 4) / (x - 3) + C (Note that the denominator remains the same, consistent throughout)
- Another correct integral is 5√(x² - 6x + 4) / (x - 3) + C
- Another correct integral is √(x² - 6x + 4) / 5(x-3) + C
Definite Integral
- ∫₀^π xsin x / (1 + cos² x) dx = π²/4
- Another correct answer is π²/2
- Another correct answer is π²/3
- Another correct answer is π²/6
Equation of Image of a Circle
- The image of the circle x² + y² + 16x - 24y + 183 = 0 reflected across the line 4x + 7y + 13 = 0 is x² + y² + 2gx + 2fy + c = 0
- The value of g + f + c is 221
Permutations of Letters
- The letters of the word OLUVME are permutated and arranged in a dictionary
- The serial number of the word VOLUME is 724
