We are given: y = 4x^3  – 5/(x^2) To find the dy/dx we are going to use the power rule, from the power rule differentiating x^n gives n*x^n-1, so from our equation differetiating x^3 will give 3x^2, but w...

Geographers bring a range of perspectives and analytical lenses to the table when it comes to climate change; perhaps the grandest problem facing the world today. As the discipline of geography is broadly...

Begin by defining fiscal policy and a supply-side improvement (the latter should be supplemented with a diagram). Following the definition of a supply-side policy, we might begin with examples of fiscal p...

First you want to draw the complez number on to an argand diagram, using which you will find the modulus and argument. This is how to do so: The modulus is to be obtained using pythagoras (which will be e...

F2 has van der Waals’ forces, whilst HCl has permanent dipole–dipole attractions. Permanent dipole–dipole attractions are much stronger than induced dipoles. More enegery is required to break the stronger...
