First substiute sin(theta) = x (This step is not nesecessary but often people find quadratics easier to solve in variables that they usually use). Then due to the fact that the "b" coefficient i...

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...
