Explanation of #19: #19 is an integral of dx/sqrt[(9+x)(9-x)] with respect to x. Start by distributing the expression inside the square root to get dx/sqrt(9^2 - x^2). Change x^2 to an equivalent form 9^2*(x/9)^2 and factor out a 9^2 to get dx/sqrt(9^2*(1 - (x/9)^2)). The factored 9^2 can be reduced to 9 and brought outside the square root, giving us dx/9sqrt(1-(x/9)^2). Time to do U-Substitution. Set x/9 = u, and take the derivative of both sides to get dx/9 = du. Substitute x/9 for u and dx/9 for du back into the equation to get du/sqrt(1-u^2). The expression 1/sqrt(1-x^2) is in fact the derivative of arcsinx, and we can take the antiderivative with our variable u to get to arcsinu. Finally, reverse our x/9 = u substitution to get arcsin(x/9) and add our constant, so the integral of dx/sqrt[(9+x)(9-x)] = arcsin(x/9) + C. Kudos to the creator for giving a clever and thematic integral that is still fairly accessible!

Can we get an explanation for the more complicated questions perhaps? I could’ve sworn that (4e)’ = 4e^3 is true but it allowed you to press it as false.

Can we get an explanation for the more complicated questions perhaps? I could’ve sworn that (4e)’ = 4e^3 is true but it allowed you to press it as false.
e is the natural constant, and so the function f(x)=4e remains a constant value whose derivative is always zero
