 Hi and welcome to the session. Let us discuss the following question. The question says evaluate the following limits in exercises 1 to 22. Limit of cos x pi pi minus x as x tends to 0. Now here we have to find the limit of a tegnometric function. You should know that limit of a tegnometric function is the value of the function at the given point. So keeping this in mind let us now begin with the solution. We have to evaluate limit of cos x pi pi minus x as x tends to 0. This is equal to cos 0 pi pi minus 0 and this is equal to 1 pi pi. Hence a required answer is 1 by pi. So this completes the session. Bye and take care.
