I don't want to be overly picky but I thought that the first integral required rather more careful treatment, and in a real interview could generate some trickier questions. For example, an examiner who wanted to stretch a candidate may ask: 1. Is it sensible to use x for both the dummy variable of integration and the upper limit? 2. Can the upper limit x take on any real value, or must we impose a restriction on its domain? If so, what is that restriction, and why? 3. With a sensible domain selected for x, what does that mean for the theta-limits with the substitution x=sin(theta)? 4. If we instead choose the substitution x=cos(theta), as we may well do, how does that change the limits of integration? 5. With the subsitution x=cos(theta), the final answer looks different to that with the substitution x=sin(theta). Does that mean that we have found a different result for the integral? If not, why not?
@theprofessor2391
2 жыл бұрын
1. YES For engineering this is an applied context. 2. The domain of the function is between -1 and one and therefore the substitution is valid. 3. Same as 2 4. You have to make sure your limits are within the domain of x. 5. Cos theta gives the same result with pi/2 - arccostheta = arcsin theta. All questions were based of real interview questions Thanks for the comments and good luck with your channel

5:30 Unless I'm missing something, when x = x, theta = arcsin(x), and this should be the upper limit. Although the correct answer was reached, I think the method was subtly wrong. The confusion comes from using the symbol "x" for 2 variables: the upper limit of the integration (a free variable), and the bound variable of the integration. Unless this is part of the test, it is clearer to use a symbol such as "t" for the bound variable.

Because the limits are being set with respect to the variable theta, not the variable x. The transformation between the two variables occurs by transforming the integrand and the differential. Admittedly, having the same variable in the integrand and the limits isn’t good mathematical practice (should use a dummy variable) but it gets the job done in this case.

Let the integral from 0 to x_ then x_=sin(theta_) theta_=arcsin(x_) the result of integral is theta. Sub upper bound arcsin(x_) into theta. The final solution is therefore arcsin(x_). Sub lower bound zero into theta will give zero.

Why exactly is the upper limit θ? If ULI is x = x’ and x = sin θ, that implies that x’ = sin θ, which implies that θ = arcsin x’. Which is technically the correct answer. You could then say that θ = arcsin sin θ = θ (or likewise x = x => sinθ = sinθ => θ=θ) but isn’t that circular logic??? Or is that valid and just a tautology.
