" If the equation "y=mx+c" and "x cos alpha+y sin alpha=p" represents the same straight line,then "

if the equations y=mx+c and x cos alpha+y sin alpha=p represent the same straight line then:

If the equations y=mx+c and x cos alpha+y sin alpha=p represent the same straight line,then p=c sqrt(1+m^(2))(b)c=p sqrt(1+m^(2))cp=sqrt(1+m^(2))(d)p^(2)+c^(2)+m^(2)=1

if the equations y=mx+c and xcosalpha+ysinalpha=p represent the same straight line then:

If Ax+By=C and x"cos"alpha+y"sin"alpha=p represent the same line, find p in terms of A, B, C.

Show that the equation of the straight line x cos alpha+y sin alpha=p can be expressed in the following form (x-p cos alpha)/(-sin alpha)=(y-psi n alpha)/(cos alpha)=r

If the straight lines ax+by+p=0 and x cos alpha +y sin alpha = c enclose an angle pi//4 between them and meet the straight line x sin alpha - y cos alpha = 0 in the same point , then

If the straight lines ax+by+c=0 and x cos alpha +y sin alpha = c enclose an angle pi//4 between them and meet the straight line x sin alpha - y cos alpha = 0 in the same point , then

If the straight lines ax+by+c=0 and x cos alpha +y sin alpha = c enclose an angle pi//4 between them and meet the straight line x sin alpha - y cos alpha = 0 in the same point , then

Reduce the equation of the line x cos alpha+y sin alpha-p=0 into intercepts form
