Read MoreHomogeneous equation in two variable. $$ $$ Homogeneous equation in two variable i.e $ax^2 + 2hxy +by^2 = 0$ always represent pair of line. Since $g=f=c=0\;\Rightarrow bg^2+ch^2+af^2-2hfg-abc=0\,\forall\,x \in R$ Pair of lines represented by homogeneous equation in two variables are $L_1:y – m_1x = 0$ and $L_2 : y – m_2x = 0$, where $m_1,m_2$ […]

Read MoreEquation of pair of straight line. What does concept of pair of straight line represent. Let $L_1\,:\,a_1x+b_1y+c_1=0$ and $L_2\,:\,a_2x+b_2y+c_2=0$ be two lines, then pair of straight line (also called as combined equation of given lines) […]

Read MoreArea of a parallelogram. The area of a parallelogram ABCD can be found by calculating area of two triangles ABD and triangle BCD. In $\Delta$ADB , $Sin\theta = \cfrac{P_1}{AD}\;\Rightarrow AD=BC=\cfrac{P_1}{Sin\theta}$ $$ $$ In $\Delta$BCD , $Sin\theta =\cfrac{P_2}{DC}\;\Rightarrow DC=AB=\cfrac{P_2}{Sin\theta}$ $\therefore$ Area ABCD = $2.(\cfrac{1}{2}.AB.AD.Sin\theta)$ […]
