Find dy/dx of the equation (x^3)*(y)+7x = y^3 + (2x)^2 +1 at point (1,1)

Use the product rule d(u.v)/dx = u.(dv/dx) + v(du/dx). Calculate the LHS as such first. (Demonstrate on whiteboard.) Then calculate the RHS. (Demonstrate on whiteboard.) Group the dy/dx terms on one side of ...

How do mutations make non-functional enzymes?

Mutations are changes to the base sequence. The base sequence determines the amino acid sequence. A different base sequence therefore codes for a different amino acid sequence. Amino acids interact with each...

Why are electron volts used instead of Joules in Quantum Phenomena and how do you convert between the two?

In quantum and particle physics, quantities such as energy and momentum are extremely small and so it is logical to have a standard unit of energies at this scale. It saves time to write 1eV, as opposed to 1...

When do I use the genitive case?

You use the genitive case to mark possession of something. It is a nice way to say that an object belongs to someone. There are some prepositions that trigger this case. In all cases you can use a simple tes...

The curve C is defined by x^3 – (4x^2 )y = 2y^3 – 3x – 2. Find the value of dy/dx at the point (3, 1).

When we find dy/dx we find the gradient of the curve at (3,1). Start by differentiating the left hand side (LHS) like so.. (whiteboard). Remember every time we differentiate a y value we multiply by dy/dx. T...
