As we are differentiating a product (two things times together) we can use the product rule which is if: y = u(x)v(x) then dy/dx = u(dv/dx) + v(du/dx). So firstly looking at our equation we need to identify ...

This question require us to rearrange the equation and solve it to find the vale of x. Firstly we need to make sure all of the x are on one side of the equation. To put all the values of x on one side we can...

Taking the student through a sample poem, here e e cummings' '1a', I would guide them to look at content, form, and images, as well as the concrete nature of the poem. I would then ask them to tease out the ...

Speed is a scalar , which means the car's speed will be a value that has a magnitude (number) only. Velocity is a vector , which means that the car's velocity will be a value that has both magnitude and dire...

If the details of the distribution - its mean and standard deviation are known, the following transformation applies Z = (X - mean) / stdev where Z is now a random variable distributed as normal(0, 1). Now, ...
