The first thing to do is to think in points; 'what points am I going to bring up for this specific question?' These points can be remembered/structured by specific scholars (e.g. Swinburne), or by specifi...

Let's first recall the definition of tan(x) = sin(x)/cos(x). Hence, y' = d/dx( sin(x)/cos(x) ). Recall quotient rule for differentiation: ( f(x)/g(x) )' = ( f '(x)^2*g(x) - f(x)*g'(x)^2 ) / g(x)^2 and tha...

Nella Prima Guerra Mondiale, l'Italia si uni' alla Triplice Intesa con Francia e Gran Bretagna, nonostante fosse stata membro della Triplice Alleanza con Germania ed Austria-Ungheria, ed ebbe ruolo fondam...

A ball is thrown with a certain launch angle (theta) above the horizontal with a certain velocity v. Let us assume that the gravitational acceleration g is constant over the flight, the ball has no...
