I tried something along those lines. cos (a*x^2 + b) = cos (a*(x+T)^2 + b) Hence, a*x^2 + b + 2* PI*k = a*(x+T)^2 + b, where is k is an integer. Which reduces to, 2*PI*k = a*2*x*T + a * T^2 So T is function of x. So the function is not periodic. But let's take an...

Hi all, Hope some here can help me with this math problem. Given, y1 = ax^2 + b. y2 = cos (y1). where a and b are constants. Is y2 periodic with respect to x.? Visually using example grpah, seems to be periodic. How do u find the exact period of such a function? Thanks in advance...
