To integrate sin(x^2), the substitution method is effective. By letting u = x^2, the integral transforms to ∫sin(u) * (1/2x) du. The result of this integration is -(1/2x) * cos(x^2) + C. It is important to note that sin(x^2) cannot be expressed in terms of elementary functions. The discussion highlights the connection to Fresnel integrals as well.

how to integrate sin(x^2)?

It can be put in connection with S,which is one of the Fresnel integrals.

It's noit expressible through "elementary" functions.

To integrate sin(x^2), we can use the substitution method. Let u = x^2, then du = 2x dx. We can rewrite the integral as ∫sin(u) * (1/2x) du. Using the formula for the integral of sin(u), we get ∫sin(u) * (1/2x) du = -(1/2x) * cos(u) + C = -(1/2x) * cos(x^2) + C. Therefore, the integral of sin(x^2) is -(1/2x) * cos(x^2) + C.

Relativistic Momentum, Mass, and Energy Momentum and mass (...), the classic equations for conserving momentum and energy are not adequate for the analysis of high-speed collisions. (...) The momentum of a particle moving with velocity ##v## is given by $$p=\cfrac{mv}{\sqrt{1-(v^2/c^2)}}\qquad{R-10}$$ ENERGY In relativistic mechanics, as in classic mechanics, the net force on a particle is equal to the time rate of change of the momentum of the particle.
