    The question is : solve the system of equations
    a = exp (a) . cos (b)
    b = exp (a) . sin (b)
    It can be nicely solved by using Lambert W function after letting z = a + ib

    I found an interesting approach to Q49. I added an integral of 1/lnx dx and also subtract it to keep the original value. Then I used IBP on the integral -1/lnx and I got -x/lnx - the original integral, so they cancel nicely. Then i just solve the remaining integral as li(x), so I got my final answer: li(x) - x/lnx +C

    if Q9 with the numerator and denominator dividing on cos²x, that would lead to dtanx/(1+tanx)² and a way for Q33 with multiplying 1-cosx up and down after decomposing the term sin2x in the denominator brings in (1-cosx)/sin³x as the integrand and results in c+[cscx(cscx-cotx)+ln|cscx-cotx|]/4 and Q35, c-2ln|cos(x/2)|; with the result of Q54, the x² term can be further operated; Q94, the result written down misleaded, π/2

    Number 9)multiply nominator and denominator with sec^2x so we get integral of sec^2x/(tanx+1)^2 dx substitue u=tanx+1 Du=sec^2x so we get - 1/tanx+1 rewrite tanx as sinx/cosx, do the calculating and you end up with sinx/sinx+cosx +constant (sorry for my bad english)

    For question 4th, substituting lnx = u, we get
    e^u.u/(1+u)² and now thinking from the derivative perspective we see that this looks like the u/v rule, and on some trial and error you come to know that it is the derivative of e^u/(1+u) and hence putting back u as lnx you get the ans, pretty much without any sort of integration.

    This is just so incredible and amazing! Also, I would love to see like some sort of competition in this between maybe you and Dr. Peyam or something like that (Maybe something like the MIT Integration challenge thing, but I'm sure you guys would make it more fun), You guys could put a prize on it too! I'm sure it would drive a lot of viewers and be much fun!

    3:28:28 I think it should be +sqrt(2pi)... instead of minus (small mistake)
