Use SUVAT for constant vertical acceleration. Solve for t. S = -10U = 0V = -A = -gT = tS=UT+(AT^2)/2t = sqrt(20/g)

Use substitutionlet u = cos(x)du = - sin(x)dxint(tan(x)) dx = int(sinx/cosx) dx = - int(1/u) du = - ln(u) + c= ln(secx) + c

We will use the cross product of these two vectors to help us find the perpendicular vector. The cross product works by finding a vector which has no effect on the position of a point with respect the the...

Benzene is stable due to its delocalised ring of electrons - which forms as a result of the carbon-carbon bonds being neither single nor double bonds, instead an intermediate length with electrons in the ...

The imperfetto (eg. facevo, era) is used for a continuous or repeated action or a description in the past. For example, if something happened everyday you would use the imperfetto, (eg. 'Ogni giorno mangi...
