Simple random samples from each of the strata are collected and also combined into a simple. This technique of collecting a sample from a population is named as stratified sampling. Stratification may be by age, occupation income group and so on.
One-to-one function: A function is called one-to-one if not any two values of x produce the same y. Mathematically specking, this is the same as saying, f ( x 1 ) ≠ f ( x 2
Solve the Limit problem as stated Limit x tends to 0 [tanx/x]^1/x^2 is ? lim m tends to infinity [cos (x/m)] ^m is? I need the procedure of solving these sums..
