What is required to check that a given equation of a circle neither touches nor intersects the coordinate axis. Say for example x^2+y^2-8x-12y+p=0 range of p such that above conditions are...
 
 
For neither touches nor intersect the axes the perpendicular distance from center of the circle should be greater than the radius.this is will give conditions and thus solve them

Is it correct because one way it says m1/m2 is +ve and ax1+by1+c)/(ax2+by2+c) To negative
 
 
Dear Student, Correction is there, On solving the equation, we get – m1/m2. So negative sign is missing over there. Thanks.

A circle passes through the point (3,(7/2)^0.5) and touches the line pair x^2 – y^2 -2x+1=0. the co ordinates of centre of circle are? (4,0) (6,0)
 
 
OK so first we solve for the lines whihc gives the two lines as and now plotting them on the coordinate axes, it’s easy to see by symmetry that the center of circle would lie on x-...

Integrate log(sinx+cosx)dx from -pi/4 to pi/4. someone plz help
 
 
This is a tricky question First put x = -x and add Now put 2x = t which implies, dx = dt/2 Now refer to the following steps to solve for the simplified integral
