                   If f(x1 + x2 + ... + xn) = f(x1)f(x2)...f(xn) for all x belongs to real; and f(0) = 2 and  f(m) > 0 where m,n belong to natural and m is even and n is odd. 


Evaluate lim ((f(x)-1)/x) where x tends to zero.

Find all the tangents to a circle (x-a) 2 + (y-b) 2 = r 2 which make an angle @ with x axis
 
 
the result is very simple for circle centred at origin we say eqn of tangents is y=mx +/- r(1+m 2 ) 1/2 for circle with centre a,b we can linearly transform the eqn. by Replacing y------>...

sorry it must be y-b=m(x-a) +/- r(1+m 2 ) ½ ( here +/- means plus or minus) in above post g must be replaced by “-a” and m is multiplied to x-a. it was my fault But your answer is wrong as...

any line of form y-b=mx-g +/- r(1+m 2 ) ½ ( here +/- means plus or minus) will touch the given circle, if we put m=tan@ then the equation of the lines are the required tangents.

Why is equation (1) not a polynomial equation and equation (2) not a polynomial in y? (1) dy/dx + sin(dy/dx) = 0 (2) (dy/dx) 2 +(dy/dx) - sin 2 y = 0
 
 
Being a equation and a polynomial equation is very different. Functions like sinx, lnx, e x are not considered polynomial quations. They are transcental functions.
