Fuck man u going to ace hsc

Double bump

Can answer the question smartass?

Bump

It's very demanding subject that requires alot of work.

Can u guys see it question 21

Question 21

Yeah i know but i just find it so much easier using the L'Hospital rule. Oh well ;0

A circular cylinder of height 6 cm and base radius 4cm sits on a table with its axis vertical. A point source of light moves vertically upwards at a speed of 3cm/s above the central axis of the cylinder, thus casting a circular shadow on that table. Find the rate at which the radius of the...

A straight railway track and a straight road intersect at right angles. AT a given instant, a motor car at 40 km/h and a train at 50km/h are moving away from the intersection and are 40km and 30 km respectively away from the intersection. At what rate is the distance between them changing one...

So basically can we use L'Hospital's Rule for lim question (lim x>0 sinx/x) etc

Cos5x+cosx-cos3x=0 domain -pie<x< pie

Cos5x+cosx-cos3x=0 domain -pie<x< pie

Integral of pie/2 to zero Cosx dx/3+cos^2(x) =0.25ln3

0/infinity= 0 that's wrong, cause when x=0 on graph x/arctanx y=1

How about when x=0 therefore arctan=0, what happens to the reciprocal.

How do u even draw 1/arctanx

Can some explain the graph y=x/arctanx

The base of a solid is the region by the graphs of f(x)=x^2 and g(x) = 8 - x^2. Find the volume of solid if all the cross sections perpendicular to the x- axis are squares.

Thanks man you are absolute life-saver !!! Keep up the good work :)
