does anyone know how to find the inverse of x=1/2(e^x-e^-x)?

i was jus wondering what the approximate raw mark would be to get a band 5 in standard english

looking at other cut offs for a band 6 at other subjects what do you think a raw mark is enough to guarentee a band 6? after all geog is not a great scaling subject, so you basically have to do good in all the sections. ill say a raw mark of mid 80s is enough

geez i need help with projectile motion, 1) find an expression for the maximum range in the horizontal plane for a particle with initial velocity Vm/s. find the two angles of projection to give a range equal to half the maximum range. 2) a projectile has a trajectory such that its range on a...

this might sound easy but i dont seem to get the answer. maybe my working out is wrong anyways heres the question. 1)a body is projected with an initial velocity of 45m/s and reaches a maximum height after 4 seconds. find the angle of projection. 2) a cricketer can throw a ball 40m vertically...
