First we take the derivative of the function, this gives us dy/dx = cos(x)
Now we work out the different x values for y = 0 and y = 1.
sin(x) = 0 => x = 0, sin(x) = 1 => x = pi/2 (90 degre...

= xlnx - the integral 1/x X x with respect to x= xlnx - the integral of 1 with respect to x= xlnx - x + c

A diagram would be very useful for this answer. At the poles, the Sun's angle in the sky decreases, so the same amount of solar radiation is spread over a greater surface area. At tropical latitudes howev...

A good personal essay should be centred around a change or experience of the self rather than a specific event like getting lost or losing a loved one. The essays should include reflection and imp...
