1+cosz= sin^2(z/2)+cos^2(z/2)+cos^2(z/2) - sin^2(z/2)
Hi sir your videos are great. A small doubt sir in some problems we keep constant c as such and in some we find the value of c by using initial conditions . How could we do it sir.
If initial condition is given in question, we find value of c, other we write it as "c" only
ok sir thanks a lot.
