Can we Simplify the Integration of Q Function with a Change of Variable?

Click For Summary
The discussion centers on simplifying a specific integral involving the Q function, expressed as ∫0,4T(Q(2∏*(0.3) * ((t-5T/2)/(T√(ln2)))dt, where T is a constant. Participants explore whether this integral can be transformed into another Q function through a change of variable. The Q function is defined in relation to the complementary error function, with references provided for further understanding. The conversation suggests that integration by parts and variable substitution may be viable methods for simplification. Ultimately, the goal is to clarify the relationship between the original integral and a potentially simpler form involving the Q function.

can we simplify the below equation into another Q function?

∫0,4T(Q(2∏*(0.3) * ((t-5T/2)/(T√(ln2)))dt
where T is a constant

I have attached the equation in the attachements

What is a Q function?
 
$$\int_0^x \mathrm{Q}(t) \, \mathrm{dt}=\frac{1}{2}\int_0^x \mathrm{erfc} \left( \frac{t}{\sqrt{2}} \right) \, \mathrm{dt}=\frac{1}{2} x \, \mathrm{erfc} \left(\frac{x}{\sqrt{2}}\right)+\frac{1}{\sqrt{2 \pi}}\left(1-e^{-x^2/2}\right)= x \, \mathrm{Q} \left( x \right)+\frac{1}{\sqrt{2 \pi}}\left(1-e^{-x^2/2}\right)$$
which can be shown by integration by parts
your integral can then be found by change of variable
 
There are probably loads of proofs of this online, but I do not want to cheat. Here is my attempt: Convexity says that $$f(\lambda a + (1-\lambda)b) \leq \lambda f(a) + (1-\lambda) f(b)$$ $$f(b + \lambda(a-b)) \leq f(b) + \lambda (f(a) - f(b))$$ We know from the intermediate value theorem that there exists a ##c \in (b,a)## such that $$\frac{f(a) - f(b)}{a-b} = f'(c).$$ Hence $$f(b + \lambda(a-b)) \leq f(b) + \lambda (a - b) f'(c))$$ $$\frac{f(b + \lambda(a-b)) - f(b)}{\lambda(a-b)}...
