1. For what values of a would the lim x→a sin(x)/x be indeterminate? How could you find the limit at this value? 2. Is it possible for a function with a domain of all real numbers to have a point or points of discontinuity?

3. Discuss the relationship between the continuity of a function at point a and the left-hand derivative (LHD) and right-hand derivative (RHD) at point a.

your limit involves trigonometric terms, such as sine or cosine, try to replace parts of the function with alternative forms of the terms if direct substitution gives you an indeterminate form. For example, if your function is f(x) = (1 - cos²x)/(sinx), you could replace 1 - cos²x with sin²x (as sin²x + cos²x = 1) and then cancel the sinx in the denominator, leaving you with f(x) = sinx.

Step-by-step explanation:

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
