    Yes. It is allowed. It only does numerical integration and differentiation, therefore it is allowed, it doesn't do symbolic integration/differentiation

    P1 Math doubts only!

    f'(x) < 0 hence np turning points as denominator always >0 and numerator -ve overall f'(x) will be -ve, hence has an inverse.

    9x^2 - 12x + 5 9(x^2 - 12/9(x) + 5/9) 9[(x - 2/3)^2 + 1/9) 9(x - 2/3)^2 + 1 This can be also written as (3x - 2)^2 + 1

    Assuming ur doubt to be bii) Its just tricky. We have to reverse the process. Its the same way we use to do to find Ar, we have Ar and now we have to find relative isotopic abundance. Let percentage abundance of 80.92Br be x and of 78.92 be 100-x Ar = 79.2 79.2 = [(80.92x) + (78.92(100-x)]/100 x...

    Moles of NaOH used is 0.045 Moles of NaOH that reacted with HCl is 0.005 Remaining NaOH that will react wid acid = 0.045-0.005 = 0.04 Hence 0.04 0.04 0.06 0.06 :)
