Elasticity of demand refers to the sensitivity of demand in relation to price. In essence it measures how much the demand for a good changes in relation to its price. We know for most goods that the deman...
sin2x = tanx Take everything to left hand side, so LHS equals 0sin2x - tanx = 0Recall double angle formula : sin2x = 2sinxcosx, also notice that tanx can be written as sinx/cosx givi...

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
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...
