[" The equation "y=sin x sin(x+2)-sin^(2)(x+1)" represents a "],[" straight line lying in "]

The equation y=sinxsin(x+2)-sin^(2)(x+1) represents a straight line lying in

The equation y=sinxsin(x+2)-sin^(2)(x+1) represents a straight line lying in

if y=sin x*sin(x+2)-sin^(2)(x+1) represents a straight line,then its passes through

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

The equation of the locus of the point of intersection of the straight lines x sin theta + (1- cos theta) y = a sin theta and x sin theta -(1+ cos theta) y + a sin theta =0 is:

The equation of the locus of the point of intersection of the straight lines x sin theta+(1-cos theta)y=a sin theta and x sin theta-(1-cos theta)y+a sin theta=0 is

Number of solutions of the equation sin^(2)x+sin^(2)2x-sin^(2)3x-sin^(2)4x=0 lying in the interval (0,(pi)/(2))]

Statement -1: If a^(2)+b^(2)=c^(2),c ne 0 then the non zero solution of the equation sin^(-1)((ax)/(c ))+sin^(-1)((bx)/(c))=sin^(-1)x is pm 1,. Statement-2: sin^(-1)x+sin^(-1)y= sin^(-1)(x+y)

The formula sin^(-1){2xsqrt(1-x^(2))}=2 sin^(-1) x is true for all values of x lying in the interval
