What is the total capacitance of a circuit containing a 3microfarad capacitor and a 2microfarad capacitor in series.

For capacitors in series (1/Total capacitance)=(1/capacitance1)+(1/capacitance2).1/C=[(1/(310^-6))+(1/(210^-6))]^-1Total capacitance=1.2*10^-6=1.2microfarad

A curve has equation y = 3x^3 - 7x + 10. Point A(-1, 14) lies on this curve. Find the equation of the tangent to the curve at the point A.

Firstly, we define a tangent as a straight line touching a curve at 1 point only.We can describe a straight line using this linear relation:y - y1 = m.(x - x1)We know a point on this...

Let p and q be different primes greater than 2. Prove that pq can be written as difference of two squares in exactly two different ways.

Without loss of generality claim p > q.Now, we try to write pq in the form pq = a2-b2 where a and b are non-negative integers.If b = 0, then pq = a2. But p and q are di...
