Answer»
To find ----> ∫ ( 3x - 2 ) √( 2x² - x - 1 ) dx Solution-----> 1) plzz see the attachment . 2) First we DIFFERENTIATE expression in bracket , d/dx ( 2x² - x + 1 ) = 4x - 1 We GET ( 4x - 1 ) , now , we FORM ( 4x - 1 ) in first bracket by taking 3 common first and then multiply and divide by 4 and then adding and subtracting 1 in first bracket. 3) now we get ( 4x - 1 ) in first bracket , now we break given intregation in to two intregations , 4) For first integration , we substitute 2x² - x + 1 = t Differentiating it we get, ( 4x - 1 ) dx = dt And then applying formula of intregation ∫ xⁿ dx = xⁿ⁺¹ / ( n + 1 ) + C 5) In second intregation we complete the whole square by adding and subtracting 1/16 . 6) Now we do a substitution x - ( 1 / 4 ) = u Differentiating both sides , we get, dx = du 7) Then we apply a formula of intregation. ∫ √x² + a² dx = x/2 √(x² + a² ) + a²/2 log ( x + √x² + a² ) + C

A and B are two candidates seeking admission to IIT. The probability that A getting selecteis 0.5 and the probability that both A and B getting selected is 0.3. Prove that theprobability of B being selected is at most 0.8 |
|
Answer» P(A) = 0.5 P(A ∩ B) ≤ 0.3 Now, USING the relationship between the PROBABILITY of two events ⇒ P(A) + P(B) - P(A ∩ B) = P(A ∪ B) ⇒ 0.5 + P(B) - P(A ∩ B) = 1 ⇒ P(B) - P(A ∩ B) = 0.5 ⇒ P(B) = 0.5 + P(A ∩ B) ⇒ P(B) ≤ 0.5 + 0.3 ⇒ P(B) ≤ 0.8 Thus, The Probability of B being selected is at most 0.8 Hence PROVED. |
