Yes, 0/0=10/0=1 and here is the solution for that. Solution: Given: 0/00/0 Let,,,0/0=a/b0/0=a/b Where a=(0.5)2−(0.5)2a=(0.5)2−(0.5)2 And b=(0.5–0.5)b=(0.5–0.5) So, 0/0=a/b=>0/0=a/b=>[(0.5)2−(0.5)2]/(0.5−0.5)−−>[(0.5)2−(0.5)2]/(0.5−0.5)−−>(11) Solving ‘a’ It is in a2−b2a2−b2 form so it's value is (a+b)(a−b)(a+b)(a−b) a=[(0.5+0.5)(0.5–0.5)]a=[(0.5+0.5)(0.5–0.5)] Replace value of a in equation (1), 0/0=[(0.5+0.5)(0.5–0.5)]/(0.5–0.5)0/0=[(0.5+0.5)(0.5–0.5)]/(0.5–0.5) 0/0=0.5+0.5=>10/0=0.5+0.5=>1 Hence, 0/0=10/0=1. But on a serious note, this isn't true. Please do not take this seriously. Actually, 0/0 is not defined or infinity. And arithmetic operations do not hold true in case of not defined or infinity. For eg. ∞ + ∞ ≠ 2∞ ∞ + ∞ = ∞

Let cosA=x then cos(π−A)=−cosA=−x Hence, cos−1x=A cos−1(−x)=π−A Adding them, cos−1x+cos−1(−x)=A+π−A⇒cos−1x+cos−1(−x)=π⇒cos−1(−x)=π−cos−1(x) This -1 is inverse here. Try to write each step clearly and you will get the answer.

ANSWER

A firm manufactures two types of products A and B and sells them at a profit of R 5 per unit of type A and R 3 per unit of type B. Each product is processed on two machines M1 and M2. One unit of type A requires one minute of processing time on M1 and two minutes of processing time on M2, whereas one unit of type B requires one minute of processing time on M1 and one minute of processing time on M2. Machines M1 and M2 are respectively available for at most 5 hours and 6 hours in a day. Find out how many units of each type of products should the firm produce a day in order to maximize the profit. Solve the problem graphically.

On July 7, HRD Minister Ramesh Pokhriyal announced a major CBSE syllabus reduction with 30% of the syllabus slashed for the year 2020-21 for classes 9 to 12 because of the reduction in classroom teaching time due to the Covid-19 pandemic and lockdown.

CBSE has rationalized the syllabus with the help of suggestions from NCERT and the same has been notified by a new CBSE notification as well.

given function is ∫(x³ - )^⅓ x^5.dx

let (x³ - 1) = t , and x³ = (1 + t)
⇒3x² = dt/dx
⇒dx = dt/3x²

So, ∫(x³ - 1)^⅓ x^5 * dt/3x²

⇒1/3 ∫t^⅓ (1 + t) *dt

⇒1/3 ∫(t^⅓ + t^{4/3}).dt

⇒1/3 ∫t^{1/3}.dt + 1/3∫t^{4/3}.dt

⇒1/3 + 1/3 + c

put the value of t in the above function,

⇒.
