radius of circle=2


so length of chord=2√2


let O be origin and P be mid-point of chord


OP=sqrt(4-2)=√2


so locus is x2+y2=2

The equation of a straight line passing through the point (-5,4) and which cuts an intercept of root(2) units between the lines x+y+1=0 and x+y-1 is?
 
 
Hello Student. Please find the solutionx+y+1=0 and x+y-1 are two parallel lines and distance between them is mod|\frac{1-(-1)}{\sqrt{2}} |So distabce between them is 2/root2 = root2So our...

sin(270-theta)= -cos theta
 
 
As u know at the Y-axis function will change. So here sin function will convert in to cos function. Sin function is -ve int 3 rd qua. so cos function will become -ve. Like, I have sin(240)...
